Hey everyone! I really need some help. I know absolutely nothing about jailbreaking and upgrading. I've recently been given a first generation iphone and its running on version 1.0.2. I want to be able to sup it up to be able to get applications and be updated. I have no idea how???? I was told to not update it on itunes or it will get locked, and I will be more or less screwed. Any help would be much appreciated! Thank you!!!
