I have a jailbroken 2g 8gb Iphone on fw 3.1. I used blackrain to jailbreak it. I have 2 questions. 1) Should i update to 3.1.2 and how? 2) After i update can i unlock it and how? I read that if jailbreaking with blackrain, you lose your unlocking privileges. Also, not sure if this matters, but my modem firmware is 04.05.04_G. I also read on iclarified that only certain basebands can be unlocked. I do not want to lose all my settings and apps. it is a pain to go to cydia and update sources. Thank you.
