Hi, I just bought an 8GB iPhone off a friend, and I've got some questions. Here's a brief hisotry of his iPhone: Bought in LA Apple store in October 2007, unlocked and jailbroken to version 1.1.2 (3B48b) done with Windows. The phone has SMBpref and Customize (from thespicychicken.com) and loaded with 400mb worth of applications. Questions I have: 1. Should I re-unlock and/or re-jailbreak the iPhone to the latest firmware? If so, what application should I use? (I have MBP on OS 10.4) 2. What is the success rate of unlocking an iPhone? Can the new programs brick the iPhone? 3. I ordered InvisibleShield full body cover, will the phone fit into the charging dock after the application of the shield? Thanks in advance, I'm new to this toy which I never thought I'd own (never did any research or follow with the iPhone news).
