I got my Iphone 3g 8gb about a year ago, Not long after I had it, I jailbroke it, things were working fine. Last night I decided that I wanted to upgrade(I had been stuck on the 2.2.1 firmware, So i downloaded Blackra1n.exe and used that but not before I loaded in the ipod2,1_3.1.2_7D11_restore.ips. It was late, and I unlocked the phone when I had no need to, and now I think I've gone and ruined my iphone!! I am currently stuck with the following: Prior to installing 3.1.2 I had 2.2.1 and modem Firmware of 02.28.00 My modem firmware has not updated, but the phone version has, and I can do NOTHING to get service back to my phone, I talked to the tech support guy on the phone for 2 hours trouble shooting tonight. Wifi works, my apps work, its just the phone doesn't have the phone part to it any longer. My options are to try and vanilla the phone, to take cydia off of it, which I also have been unable to do, and once I do that I can take it to At&t and get a replacement for considering its still under warranty. ...however I would prefer just to get the damn thing working. The simcard switch did not work, my simcard WORKS in other iphones. Working iphones simcards DO not work in my phone. I put ultrasn0w on the phone at some point late last morning and unlocked it and it's been downhill since then considering I didn't need to do that Installed ih8sn0w iREB -v 3.1 for windows and used that a few times as well as resetting and reinstalling and rolling back to all the backups ive had. Please any help would be greatly appreciated. Thanks im drowning here. Dickey.
