So I followed the definitive 1.1.3 upgrade guide perfectly (3 times) but I still cant get it to work right. What did I do wrong? Heres what I did. I bought a week 50 brand new 3 days ago. I downgraded to 1.1.1 so I could get the official itunes 1.1.3 (and latest baseband) upgrade through itunes. I then downgraded back to 1.1.1, jail broke that, upgraded to 1.1.2 and jail broke that as well. Finally, ending up with a 1.1.3 iphone with latest baseband with full functionality. Just no cell services. I applied the steps at the end of guide and reset the iphone and the cell service did not come on line, but the rest of the phone still worked. WHen I reset a second time the phone relocks to a recovery/connect to itunes screen and I have to start over. I can not pull the phone out of this mode with ibricker. I am on a PC if that makes a difference. Please help! Thanks!
