Ok, after several attempts using my AT&T sim card, I now have 1 bar on the upper left hand corner, however, no 3G and then about 15 seconds later, it says no service.
 
I don't get it, why are you unlocking if you are going to use the iPhone with an at&t sim.

BTW, if you are on 4.2.1 you can not unlock thru ultrasnow, you have to replace the iPhone's baseband for the iPad's baseband in order to unlock.

I'll bet if you just jailbreak without unlocking you would not have the issues you are experiencing. Give it a try!

Also, after jailbreak you should install fakeclockup to improve the 3G.

Again, like I mentioned in my previous post, when I did a jailbreak on my iphone, I tried without unlocking. It kept saying "searching" for about 45 minutes. So, I rebooted the iphone and then I did get 1 bar, however, it did not say AT&T and then about 15 seconds later, it said no service.

I did jailbreak again for the 3rd time without unlocking and I got the same results (please see above paragraph)
 
By the way, I did install fakeclockup and it works great WITHOUT the SIM card. However, when I put the SIM card in, it is slow.....but....when there is 1 bar with no AT&T on the upper left hand corner, it is good. Could the iphone be sluggish because it still says its "searching"????

Ok, the only think that I can think of is to restore once again but this time as a new phone, not from a back up ( don't know if you already did this). See if you're still getting the not supported SIM message after this.

If you are still getting the message, then probably you have a bad SIM as stated before.

I did restore and as a new phone in itunes and I still have the same issue.

I tried a friend's AT&T SIM card and it says the same thing as well....it still "searching".
 
You say you have an iPhone, that you are an AT&T customer, but that when you put AT&T SIMs in your iPhone, it says that they are "not supported."

...except for when you jailbreak with redsn0w (which will "hacktivate" your phone) and unlock with ultrasn0w, and then it works for you. Or, at least it did in the past.

This can only lead me to one conclusion:

You don't have an AT&T iPhone.

Did you purchase this iPhone outside of the United States?

If this is in fact the case, then you are going to have a hard -- if not impossible -- time getting your phone to work again with your AT&T SIM card. When you updated the main phone software, it also updated the software on a second chip inside the phone, called the baseband. The baseband processor is the component that communicates with your cellular provider and which also happens to enforce "SIM locks": arbitrary restrictions put in place by the original phone carrier that prevent the phone from working with any SIM cards other than their own.

The ultrasn0w unlock tool currently only works with "older" versions of the baseband software. It exploits security holes in these versions, and once it gets past the baseband software's defense mechanisms, it injects custom code that causes the baseband processor to accept any SIM.

Apple is constantly updating their code to prevent these hacks from working, and the latest baseband version is not (yet) unlockable; whether it will ever be unlockable is an unknown. Even if you try to install ultrasn0w, you will not be able to use your SIM if you installed the latest baseband.

And once the baseband has been upgraded, you're stuck with the new version. You cannot downgrade the phone baseband.

For the iPhone 3G, there is a workaround that someone managed to develop, but it is not one without a significant amount of risk: you can load the iPad 3G's baseband code onto your iPhone 3G (since the iPad and iPhone 3G happen to use the same baseband chip), and then install ultrasn0w. Unfortunately, if you do this, it cannot be undone, AND it will cause the GPS receiver in the phone to stop functioning, so you'll lose GPS entirely.

I wish I had a better answer for you. :( Do you know what carrier this phone used to be on before you unlocked it to be used on AT&T? It's remotely possible that you might be able to contact that carrier and ask them to unlock the phone for you...many overseas telephone carriers are much more willing to unlock their phones after the original contract period is over than many U.S. providers are.

I appreciated that you have replied to my thread. However, I have already explained several times in this thread that I do NOT get the message that my iphone is NOT supported. Please read my FIRST post.

Look its very simple. When I jailbroke my iphone thru redsn0w, I did NOT unlock the phone. I put my AT&T SIM card and all it did was just say "SEARCHING" for about 45 minutes. Therefore, I installed ultrasn0w thru cydia in the hopes that it would unlock it. However, it STILL said "SEARCHING".

I have restored my iphone and jailbroke it again thru redsn0w with the SAME RESULTS.

When I first got this phone, it WAS working with my iphone using my AT&T SIM card. However as stated in my FIRST POST, 6 months ago, I connected my iphone via itunes and it ask do you want to upgrade....and I ACCIDENTLY hit yes, when I should have hit no.

Apple is constantly updating their code to prevent these hacks from working, and the latest baseband version is not (yet) unlockable; whether it will ever be unlockable is an unknown. Even if you try to install ultrasn0w, you will not be able to use your SIM if you installed the latest baseband.

I am now confused. I thought when you upgraded to the latest iOS 4.2.1, you can jailbreak and therefore unlock thru ultrasn0w via cydia. Are you saying I can't use my AT&T SIM card? I thought that was the whole point in unlocking your iphone.
 
Simple question. Where did u buy your iPhone. I'd its bought in Canada u will need to unlock it.

You berate me for not reading your posts (even though I clearly did), but you obviously did not read my response thoroughly. Therefore, I will try again:

If you upgraded your software to 4.2.1, that means you upgraded your BASEBAND to 05.15.04 (Settings -> General -> About, scroll to the bottom and look for "Modem Firmware").

This BASEBAND is NOT UNLOCKABLE. Period. Not with ultrasn0w, not with anything. If you need an unlock for your phone, you are screwed (unless you are willing to try the iPad baseband hack).

If you actually had an AT&T iPhone and you put an AT&T SIM into it, you should not need to unlock your phone for it to be usable. This is why so many people in this thread are confused: they are ASSUMING you purchased the iPhone IN the United States FROM AT&T.

However, by simple logical deduction, the fact that you had to unlock the phone in the past (before you updated it, when you were still running 2.2) for your AT&T SIM to work means you probably don't have an AT&T iPhone.

So, again, the QUESTION IS: where did your phone come from? From a different wireless carrier outside of the United States? If so, which one?

When I first got this phone, it WAS working with my iphone using my AT&T SIM card. However as stated in my FIRST POST, 6 months ago, I connected my iphone via itunes and it ask do you want to upgrade....and I ACCIDENTLY hit yes, when I should have hit no.

I understand this. But you ALSO said that before you accidentally updated it, your phone was also unlocked then, too. That is why your AT&T SIM worked in your phone 6 months ago. Now that you have updated to 4.2.1, which includes a baseband that cannot be unlocked, you can't use your AT&T SIM anymore. It doesn't matter whether you install ultrasn0w or not: It. Will. Not. Work.

The point that everybody else is trying to make is that if you actually had an iPhone purchased from AT&T, you would have been able to update the phone with NO CONSEQUENCES. Clearly, the update you said "yes" to had consequences attached to it: your phone no longer accepts your AT&T SIM. Therefore, this phone HAS to have come from outside of the country, and is LOCKED to a different provider.

I am now confused. I thought when you upgraded to the latest iOS 4.2.1, you can jailbreak and therefore unlock thru ultrasn0w via cydia.

Wrong. If you update to the official release of 4.2.1, you can jailbreak, but the unlock will no longer work. (If you had updated to a custom 4.2.1 that omitted the baseband upgrade, you would have been fine.)

Jailbreaking and unlocking are two completely different things. You have to be jailbroken before you can unlock, but the point of jailbreaking is not to get to the unlock. The point of jailbreaking is to be able to run apps on your phone that are not just from Apple's App Store. The point of unlocking is to be able to use whatever SIM in your phone that you want to use.

And just because you can jailbreak does not mean that you therefore can unlock. One does not follow from the other. For the unlock to work, certain prerequisites must be met, only one of which is to have a jailbroken phone. Another prerequisite to an unlock is a version of the baseband that CAN be unlocked. The baseband that Apple included with 4.2.1 is not one that currently can.

Your phone is now locked to whatever original carrier it was purchaed from for the forseeable future. There is no "undo" button on this. You're stuck unless you decide to try the iPad baseband hack on your phone. (That, or simply wait patiently for a new version of ultrasn0w, which may or may not ever appear.)

That's why he asked if you bought your phone outside of the US. If that's the case, that phone could've been locked to O2( since they had a brief exclusivity) and it worked here because it was unlocked. Once you updated you locked it again.

If you bought your phone from AT&T or you are sure that is an AT&T iPhone, then you may have a problem with the hardware and it will have to be replace.

You can jailbreak 4.2.1 but you can not unlock it unless you change the new baseband to the one of the iPad and that hack is NOT reversible. Once you do it you can NOT install stock firmware and revert to the current stock baseband.

If your iPhone was from the US, it should run on AT&T whether its not jailbroken, jailbroken or even unlocked.
That is why its important to know where your phone is from... so....
Where did you get your iPhone from?
 
You berate me for not reading your posts (even though I clearly did), but you obviously did not read my response thoroughly. Therefore, I will try again:

My apologizes if you thought I did berate you because that was not my intentions. I guarantee you if you were to speak to me on the phone, it would be exactly as I have explained in this thread. Its hard to understand a person thru a message board. Again, my apologize.

I am starting to get very frustrated...not with you or anyone. After I hit restore via itunes, I tried to get jailbreak again thru redsn0w, however, I have tried for over 40 minutes in getting my iphone past the stupid itunes logo and the usb picture. I can't get past this no matter what I do.
 
By the way, when I did jailbreak, I did have the modem firmware of 06.15.00 running iOS 4.2.1. But now that I can't even get past the itunes logo and the usb port, I don't know what else to do. This all happened when I did a restore just over an hour ago.

That's why your having trouble restoring. You can not restore to stock firmware with the 6.15.00 baseband.

I believe you can kick it out of recovery mode with tiny umbrella, I'm not really sure.

I still can't seem to understand whether you are using an iPhone from the US or from another country.

Either way, if you upgraded to 6.15, then I think you'll need a custom firmware to restore it.

Where's AppleJuiced?

I bought the iphone on ebay in 2009 and the seller was from Canada. It worked perfectly until 6 months ago when I connected my iphone to itunes and when itunes detected an upgrade, it asked if I wanted too. I "accidentally clicked yes when I should have clicked no.

Here is a helpful tip.

People on this forum (myself included) are willing to help others find a solution to a problem they may be be having with their iDevice, but we can only do so much with a lack of details.

From the very beginning you continually fail to mention (Post after Post) the fact that your iPhone originally came from Canada, that makes a big difference as to why your SIM card has been failing since the update six months ago, and why it is failing now with this new update. Like others have already said, their is no current method through ultrasn0w for unlocking your iPhone once it has iOS 4.2.1 (not yet they though).

I appreciate everyone's help, however, there is 2 pages of my thread, therefore, I don't think I was lacking in details. It would be nice to just go forward instead of backwards.

Again, like I mentioned in my previous post, my iphone that I bought in 2009 from a guy in Canada was working great. However, when I connected my iphone to itunes, it ask if I wanted to upgrade and I accidentally said yes....that was 6 months ago. Had I not said yes, my iphone would have still worked.

Within the past 3 days I have successfully jailbroke my iphone, however, I just couldn't lock it....with or without ultrasw0w.

So are you saying because my iphone is jailbroken to 4.2.1 that I cannot unlock it?
 
Ok, ...

... we try to help, but first let us get some things straight:

1. We need accurate and detailed information on questions posted by members of this forum. Don´t look back on refraining former posts, ok?
2. You need to translate any advice exactly as described, stop doing anything on your own, it doesn´t help at all.

It´s not to insult you, but to get the story and the right tools to reanimate your iPhone to life again. All of us at one point of time started this way, by help of others, now it´s your turn. See it this way: A carpenter can do amazing things with a plan and a saw, but nothing at all with a phonebook and a powerchord, got it ;-)

My summary so far: You have an iPhone 3G with iOS4.2.1 and baseband 06.15 installed. The iPhone needs to be restored, but iTunes doesn´t allow it. You are on AT&T at the moment, but the iPhone is from Canada, therefore you must unlock it by any means.

---

I would recommend, that you forget anything of how you felt about and used your iphone before - it´s gone and will never come back: You updated to the latest firmware and lost the possibility of an unlock at the moment. You had an old jailbreak and Cydia version installed, so it is not very likely that you have your SHSH hashes saved. That means, you are stuck at iOS 4.2.1. You seem to have installed the iPad baseband (06.15). You should be able to unlock, BUT you can´t restore your iPhone the normal way via iTunes. You must create a custom firmware.

---

First of all, the custom firmware: You need a software called "Pwnage" (version 4.1.3) and the original iPhone 3G firmware file for iOS4.2.1. You can grab such a firmware file here, too: http://www.megaupload.com/?d=681MCLXO . You need another software called "TinyUmbrella.

To do a custom restore with iTunes, you need to hold the option key on your keyboard while pressing the "restore" tab in iTunes. A file dialog pops up and you now must to choose the downloaded firmware file. Let iTunes it work its way. iTunes might end up reporting an error 1015 or similar. If that´s the case, startup "TinyUmbrella" and click "Exit recovery".

Now, there might be a remedy, as you say, you have an iPhone 3G and it was running iOS 2.2 when bought. There is a slight chance that you own one of the early 3G units with a specific bootrom (05.08). Those units can be downgraded via a software called "Fuzzyband" which is available through "Cydia". You seem to be familiar with "Cydia", so here comes my second advice: Go into "Cydia" and search for "Fuzzyband", then install and watch out, whether you can downgrade your baseband. Do it, if you can (here is a good guide you can lean on: http://www.iphonehacks.com/2009/05/...grade-baseband-from-023003-to-022800-for.html).

Report back about the outcome.

Yes, that is 100% correct that I have 3G with iOS 4.2.1, baseband of 06.15. And yes, that is correct that itunes won't allow a restore because after restoring the iphone, I get a message "the iphone could not be restored. An unknown error occurred (1015)".

I have no idea what "SHSH hashes" is. I used redsn0w to jailbreak my iphone yesterday morning and it was successfully. I heard that you were supposed to check "ipad baseband" with the new version of redsn0w, therefore I did check it.

First of all, the custom firmware: You need a software called "Pwnage" (version 4.1.3) and the original iPhone 3G firmware file for iOS4.2.1. You can grab such a firmware file here, too: http://www.megaupload.com/?d=681MCLXO

Thank You very much as this is what I have been looking for. If I downloaded a custom firmware, I didn't know if I should still use redsn0w or pwnage....now that I found my answer, I will download pwnage and the custom firmeware from the link you provided, and post my findings.
 
You ...

... don´t need to, please read carefully: The mentionned custom firmware file you can download is already made for your iPhone 3G. Just download it and restore as described above.
 
Since my pc wasn't working for the past couple of days, I was able to restore my iphone on my laptop. However, I couldn't restore to 4.2.1 because my laptop kept freezing up. So I found 4.0.1 instead and my iphone is jailbroken and unlocked. I want to thank everyone so much for your help.

I guess I will have to get a data plan to the iphone.
