I just jailbroke my sister's iPhone 3G running OS 3.0. The jailbreak process went smoothly, and when I tried to add ultrasn0w in the Manage Sources section, I received the following error message: After that, *all* sources in Cydia failed to be listed in the Manage Sources section. I tried rebooting the iPhone, and now, Cydia won't even open at all. It gets to the Loading Data screen, and quits. I can't ssh into the phone because I never even had time to install openSSH. I even tried doing a full restore, but iTunes 9 won't let me restore without upgrading the firmware to 3.1 (and I did try holding down both option and shift, nothing works). The thing is, I *need* to jailbreak this phone tonight...she's going abroad tomorrow and needs to be able to use the phone with a different SIM card. Any help would be GREATLY appreciated!!!
