Anyone having an issue with "not available" for network. The new baseband isn't working after my downgrade. I have 2.2.1, and the new baseband, but no service... Any help is appreciated.. Thanks.
Update -- Forget it. You guys are life savers.... I was not reading the instructions exactly as they were said.
Thanks again.

3.0 -> 2.2.1
UPDATE!!!
Before you start any of this make sure your iPhone is still in 3.0, if you downgraded it and cant get it back to 2.2.1, UPGRADE IT AGAIN then do this. Its tedious but it worked for me and hopefully with some luck it will work for you.
1) iPhone must be in O.S. 3.0 *IMPORTANT*
2) Enter DFU mode with the iPhone
3) Restore to 2.2.1, and receive Error 1013, or something similar, its fine, your phone is in 2.2.1 so move on.
4) Reset iPhone by holding Home and Power for 15 seconds, release and hold Power for 2 seconds (it does not matter if your phone comes back on after 13 seconds, hold it for *15*)
*NOTE* at this point I was actually able to access my phone without jailbreaking it *NOTE*
5) Open QuickPWN, enter DFU and let QuickPWN do all the work.
6) Be glad you still have an iPhone and not a brick =)
If this doesnt work for you, please try to attempt it from scratch on Windows, I think that might have something to do with step 3), but Im not sure.
Good Luck!

the problem i am having is quickpwn dont see my phone. it just sets there saying "please connect the device...". how do i get this to pick it up?
Same. Here's what I tried (and it appears to be working but not completely finished yet... oh yes it is! Woo hoo.)
Ok, trying to remember exactly what I did... I tried doing a DFU restore in iTunes as has been described and then I was just at the screen with the arrow and iTunes.
I then opened up pwnage tool and click on the 3G, clicked on the ipsw and it made it. Then it said "go to DFU" and you just follow the on screen instructions (hold power and home for ten, let go of power) Then it'll tell you to go to iTunes and then do an option-restore and choose the ipsw you just made in pwnage and you should be good to go. One thing I noticed is that I got the all white screen on the iPhone (which I handn't before) so if you see that then it should work.
Is this completely different on an iPod Touch?
Somehow, I successfully managed to restore my iPod to 2.2.1 without needing to jailbreak. And surprisingly, no error ever came up!
Syncing and everything worked fine. But I still had to try like 5 times to get into dfu mode correctly.

Help
My phone just sits on the apple screen while its "Preparing iPhone for restore...". It doesn't give an error, it just stays on that screen. Any suggestions?
ok update... I let it sit for awhile, got error 1604 when I came back. I followed instructions up until quickpwn. After I hold power + home for 15 seconds, holding power for 2 seconds does nothing. I can hold home for 2 seconds to get to the emergency dial thing. Is that what I need to do?

I liked iPhone 3.0, however I was having a lot of trouble syncing, it take a lot of time, and sometimes the songs disappeared. So I restored my 3G to the 2.2.1 firmware using the instructions posted above and it worked.
A small piece of advice: Be sure that iPhone is in DFU mode and not recovery mode. You can tell because on DFU mode the screen stays black, while on recovery mode it gets stuck on the Apple logo. After I figured that out it worked perfectly.

1604 error
Ok I solved my 1604 error. I was putting the phone in recovery mode, not DFU mode.
Here is a guide for DFU mode. Basically you want the computer to recognize it before anything(at all, even logos) comes up on the iphone screen

Hope this helps

What if they DO "have ideas of what their(sic) doing" and they don't have as much money as you do - i.e., enough to have a separate device? They shouldn't post their questions here because they annoy you?
It's already bricked a phone for me, and iTunes seems mucked up by the SDK install, AFAICT. (yes, I read the docs).

Finally Solved this!!!
Ok, finally I downgraded! OMG, it took all day.
I was having the same problems as many others. I'm on Mac 10.5.6 and I guess they did something to the USB driver, because for the life of me, QuickPwn wasn't finding my phone.
I ended up going to a friend's house who has a PC, having him install iTunes on his PC, then running QuickPwn from there, and FINALLY it works! I thought I was going crazy. Here is a quick recap of how it all went down:
Downgrading from iPhone 3.0 back to 2.2.1 on a Mac OS 10.5.6 (in plain English):
1) Make sure you have 2.2.1 firmware in order to go back. This should be in your home/Library/iTunes/iPhone Software Updates. If you don't see the firmware update in there, then you can download them from Apple at the following locations:
iPhone 3G 2.2.1:
http://appldnld.apple.com.edgesuite...90127.aQLi8/iPhone1,2_2.2.1_5H11_Restore.ipsw
iPhone 1st gen 2.2.1:
http://appldnld.apple.com.edgesuite...90127.Mmni6/iPhone1,1_2.2.1_5H11_Restore.ipsw
2) Make sure you don't have a passcode on your device. I found this can make it harder to fix sometimes.
3) Connect to to your computer with USB cable, launch iTunes.
4) With the phone ON, press and hold the top sleep/wake button and the home button at the same time for 10 seconds. The phone should turn off at about 5 seconds. At 10 seconds, release the sleep wake button and just keep holding the home button for another 15 seconds. iTunes will detect the device is in DFU mode. (The screen should NOT be on. If it is, then repeat this step and try reducing the first 10 seconds to more like 8 seconds.)
5) Hold down Option (mac) or shift (pc) and click on the "Restore" button. Choose the new 2.2.1 firmware for your device.
6) About three-fourths of the way through, you'll get error 1013 and the phone will restart in recovery mode.
7) Launch QuickPwn and a message will ask you to hold down sleep/home buttons for 10 seconds. IF QUICKPWN CANNOT FIND YOUR PHONE and you're using Mac OS 10.5.6, then you need to find a PC and install iTunes & QuickPwn. You don't need to jailbreak your phone. Just that first step on QuickPwn will do. Once you get the slider bar (to unlock) go back to your machine, and sync as normal and it will copy your backup back on to your device.
QuickPwn doesn't work on virtual machines, so parallels won't work.
Damn, one little thing like that just ruined my day. But finally glad to get that solved.
Maybe someone found another way to get quickpwn to recognize on 10.5.6?

RE: Finally Solved this!!!
thanks for giving that. i thought i did the usb driver stuff but maybe it didnt work. i got 3.0 working now thanks to mocgue. i will say this, 3.0 is pretty nice but mms dont dont work and everything is a little glitchy. its a good trade off for an unjailbroken 2.2.1 but i wish i still had the jailbroken 2.2.1. id say dev team will have a fix for this soon though.
