Ok heres my situation. Ive had the iPhone since the day it came out. And earlier i saw some of the things that Installer.app is capable of.. i thought it was all pretty awesome. My question goes out to all you hacking, unlocking and jailbreaking guru's: I have a legit AT&T iPhone and I have a legit 1.1.3 upgrade from iTunes. Ive been up all night trying to figure out the easiest way to get installer.app on my phone so i can use all the cool features.. can someone PLEASE guide me in the right place? I was following along with the Definitive guide to jailbreaking and whatnot, because i thought you had to jailbreak your phone before you can use installer.app? am i wrong?
