I have a 4 gig iphone (2g) which i jailbreaked and unlocked to version 2.2.1 problem is No SIM card installed. i'm wondering if it is because i did the unlocking, jailbreaking wrong ( i didn't have any problems with the process , it went perfect) or because previously i had a problem with the sim tray not going into the iphone. it would go like 95% of the way in then stop. i thought it might be something that got bent and is blockin the way, so i put some little thing in and wedged it into place. ( i can put the sim tray with the sim card in now) i'm tryin to use the iphone with Rogers or Fido. (Cell phone providors) didn't work with either. this is the second time i jailbreak/unlock my iphone. ( the sim tray problem happened before the second time around of jailbreaking/unlocking. HELP!!!!!!!
