    Hey!

    I'm not sure there is a way that has been figured out yet on how to downgrade baseband from 3.0 to the current stable firmware, but I'm curious as to know.

    I know it was available before for prior firmwares, but not this.

    Anyone know?

    Nope, I haven't heard anything yet.

    It doesn't seem it makes a difference. I haven't encountered any problems with the updated version...

    Are you sure you downgraded back to 2.2.1 properly?

    Yep. I'm back at the 2.2.1 fw.

    I've just noticed with 3.0, some apps don't work/properly.

    Is it possible to downgrade from 3.0 to 2.2.1 on an iPhone 3G on a Mac? I heard that you *need* the windows version of QuickPwn to get it out of recovery mode. Is this true?

    Does anyone have a custom firmware that would downgrade the baseband?

    I think that no one has found a way to downgrade the baseband is the iPhone 3G. That is why the Dev-Team stated that if you updated to 2.2.1 directly from iTunes, then you would lose the ability to use yellowsn0w. If there was a way to downgrade the 3G's firmware, they would've done it already.

    Yeah. Come on Spaz I know you know this.

    Just do a search.

    What it comes down to, in summary, is 10.5.6 blocked the iPhone going into DFU, so you have to put the 10.5.5 IOUS.

    DFU the sucker and do pwnage/quick pwn.

    Finish. Then reinstall the 10.5.6 IOUS.

    You need a free ADC account to get the proper files.

    Dude. I already did my searching. You didn't read what I said.

    I know how to DFU... I've already installed the 10.5.5 USB drivers... I know how to downgrade. Here's the catch. From what *I read*, people have had to use the PC version of QuickPWN to get their iPhone OUT of recovery mode after iTunes errors out. From what I was reading, they said that the Mac version of QuickPWN wouldn't kick it out of recovery and they needed to boot into Windows to get it out. I know what I'm doing, but I don't know if I really want to take the risk... just in case I want to downgrade (knowing me, I would). You're cool and all, but don't just assume that I didn't search. I know more than most about iPhones. I need to get out more ;)
