I am not new to jailbreaking but have never had to unlock before. My 3gs has been unlocked and resting happily at 4.3.3 since, well so long I can't remember. I have an iphone4 (unlockable bb), ipad 2 (which was on 4.3.3 until the a5 jailbreak was released) and an itouch. I have learned all about jailbreaking after a yr of having a friend do it for me and been doing my own since.
My issue is, all of my devices are on 5.0.1 except the 3gs which is unlocked since I am on tmobile. I love the features of 5.0 firmware like cloud and wifi sync and want them on my main phone. However, I don't know where to start since I need an unlock as well. My friend ended up giving me the 6.15. ipad bb a yr or so ago so I am not sure it even matters.
Can my old bootrom 3gs on 6.15.00 baseband be updated to 5.0.1 then rejailbroken, unlocked? Do I need to preserve BB? I read 6.15 is irreversible so anything special I need to do to ensure I can use this phone with tmobile after getting up to date with 5.0.1?
