I was going to sell my unlocked iPhone 3G so I could sell it locally, then buy an iPhone 4. My friend accidentally upgraded me to 4.1, then, I went back to 3.1.3, but the damage was done.... Baseband: 5.14.02 Bootloader: 5.09 non-unlockable ...so, as an alternative, I was just going to sell my mom's iPhone 3G instead, it is jailbrakable and unlockable... but her power/lock button does not work (I've researched tons of solutions to this on google/youtube, none work). Since that button on her phone doesnt work, I cannot unlock to sell hers either. FML i suppose i have joined the ranks to wait for dev-team's upgraded ultrasn0w release. Just wanted to share my story, and wondered if anyone else had another one similar.
