I am already kicking myself in the head for this but my dad and I both got ourselves the iPhone 3Gs, currently at 3.1.2 with baseband 05.11.07, jailbroken with Blackra1n and sn0w installed for use on T-Mobile USA. My phone works fine with no issues, however, my father deleted the blackrain and cydia apps from his phone. The phone still works on T-Mobile with no issues but he can not download different fixes and app from cydia. What can I do to return the Cydia icon back? His phone does not have SHSH backed up nor does he have SSH enabled to respring the icon. My best guess would be to restore it or upgrade it somehow to get Cydia back or somehow remotely respring Cydia back.
