baseband

For those of you who are wishing you hadn't upgraded to 2.2.1, iPhone hackers pH, BigBoss and EvilPenguin have creted a new tool for downgrading your baseband from 02.30.03 back to 02.28.00, restoring it's ability to be unlocked using yellowsn0w. The hack will work on any devices manufactured prior to September 2008 with the 5.8 bootloader, though iPhones with the 5.9 bootloader cannot be downgraded.

Well, the 2.0.1 firmware update has been released, and users are reporting problems. Not too surprisingly, first-gen iPhones that have been jailbroken and/or unlocked are un-jailbroken by the update, so you'll lose access to all of your unofficial, third party apps. The Dev Team is already hard at work on an updated Pwnage tool for 2.0.1. However, the update is a little more serious for iPhone 3G owners.
