Hey all, I am a total beginner when it come to unlocking Iphones. But I was hoping I could ask you guys a few questions. I have an Iphone 3GS, iOS 4.3.5 and the bb is 5.16.02. Now, I know that it is pretty tough to unlock this one. However, I was wondering, since I haven't upgraded the software on the phone in over a year, what would happen to those settings, if I actually did an upgrade. Would the bb change, if I installed a software upgrade? And if it changed, would the process of unlocking the phone be any 'easier' after the upgrade? What firmware package would be the best to get it unlocked with? I'm sorry for asking these absolute beginner questions but I would appreciate it, if someone replied. Thanks.
