For some reason my new iPhone 4 couldn't create a backup. So I finally just decided to restore and start over to see if that would fix it. But now I'm stuck, and can't restore. On one of my computers it gets stuck at the preparing iPhone for restore screen, then eventually gives me either a 1602 or 1604 error without ever loading the rom. On my other computer it goes through the restore process, and has the progress bar on the iPhone, then eventually give me a 3014 error and goes back to the iTunes screen. I've uninstalled and reinstalled iTunes 9.2 on both, deleted and redownloaded the firmware, and searched endlessly for a solution. Nothing seems to work. Help please! I've been trying to get my new phone working for hours now, and can't get it to restore.
