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.
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)
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."
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.
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".
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 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.
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.

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

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:
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.
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.
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).
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.
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
