I am fairly new to the iPhone scene at this time. I have been doing as much reading as I can, and I sincerely apologize if someone has already answered these questions. 1. I would like to jailbreak my iPhone 1.1.3 OoTH (16gb) using the ZiPhone method. Do I need to use the unlock function if I have a valid AT&T contract? 1a. If I choose not to unlock it, will it still break the locateme functionality? 2. To restore to a clean locked 1.1.3, I just restore it via iTunes, is this correct? 2a. If I chose to simply restore it, does it completely erase everything that may have been installed via a jailbreak (ex. would it free the used memory that was occupied by the apps, not just not allows access to them?) Thank you for your answers.
