General Info: Okay, it has been officially 2 days of non stop google searching lol. Okay, yesterday I was doing my normal Cydia browsing(WHICH I ALWAYS DO), when I found a few little apps that I liked, well b/c I do not have wifi and my speed is not that fast seeing as it is 2G T-Mobile so I used Cyder to download the apps and used iFunbox to upload them to Cydia. That did not go to well seeing as I rebooted my phone and the "CTI(connect to itunes)" screen of death showed up. I have tried almost everything, see I said almost, I do not know if their is anything I am missing. This is what I have done. I use windows btw. Programs: Used iReb, Redsnow, sn0wbreeze, Recovery Fixers(TinyUmbrella,iRecovery,etc.), Custom Firmware(S) like 3 or 4, Downgrading. I have searched all kinds of forums for the answer, and tried everything from the ones I have looked at, nothing works. Error: These are the errors I get, 1600-1604 nothing but those and between those, no 1015, 39..etc just the 1600-1604. System Info: iPhone 3G, Baseband 06.15.00, Jailbroken 4.2.1. Final: I would really appreciate if someone could help me out, if not I will just lay and cry lol, cause I ish not rich lol.
