I've never needed to unlock any of my phones until now (taking a trip to Asia next month), and after rummaging through a bunch of old stuff I had laying around, I found my old 3GS, still running 4.0, with the 5.13.04 baseband. (I guess I'll have to live with the "downgrade" from my 4S to the 3GS while I've overseas...) So here's the stupid question: How do I go about safely unlocking it? (update to 5.0.1 w/o updating the baseband?) I've done some searching, and it seems to be possible with this baseband, but given the "extreme" age of this device, I haven't been able to find any tutorials around to walk me through it step by step. (I think I read something about Ultrasn0w 1.2.4 using the iPad baseband, something I didn't think was necessary with 5.13.04?) If anyone could help out, I'd really appreciate it.
