I just recieved an unlocked iphone and it was working perfect with my t-mobile sim card. i was getting to know the phone, pressed the unlock button, and it said something about "all files found, wait 20 mins". after that, i haven't had service, no network is found, and i can't call, etc. i'm so new to this! i need someone's help. i go into the installer and everything in there tells me "error, cannot allocate memory"...i have no idea what to do, is my iphone bricked?? how can i get it to go back to the way it was??? i have the installer v2.63 and in the version 1.0.2....that's all i know.
