Those of you who recently unlocked their iPhones running iOS 4.2.1 or 4.1 know that the process wasn’t as straightforward as we expected.

All theses days you have been told that, Baseband cant be downgraded right? Well, it looks like that is going to change. Yeah! You heard that right. Soon, you should be able to downgrade your baseband.

The latest UltraSn0w unlock works for the iPhone 3G or iPhone 3GS with baseband 04.26.08, 05.11.07, 05.12.01, or 05.13.04. It also works with iPhone 4 with baseband 01.59.00. But if you’re iPhone is on a different baseband, you have to upgrade to 06.15.00, either using RedSn0w or PwnageTool.

This new unlock doesn’t come without its share of issues, with battery drain for some of us, and/or GPS issues for others. Fortunately, it seems the Dev Team is working on a baseband downgrade method, which would make the unlock process easier, and safer…

From what I understand, the goal would be to allow an iPhone with the 4.2.1 baseband to be downgraded to 04.26.08, 05.11.07, 05.12.01, or 05.13.04, to then use UltraSn0w to unlock. Apparently, this baseband downgrade method might also work for baseband 06.15.00. Read more…
