[Zac300]

I was messing with my husbands fone it used to be jailbroken but, in itunes a screen popped up and said upgrade to 2.1 ,so i did (bad idea). at the end it said it did not recosnize the sim card, we were using t-mobile for it. it keeps asking to insert a at&t sim card, but i dont have any or any at&t services...


Im not sure if the iphone is 2.1 firmware or the old one...
can someone help me


i really need to use the fone....

on the iphone screen its just a picture of the usb and itunes logo and only for emergency calls.

I think the unlock in your phone was a temporary one and hence when you updated it..the lock got reverted.I suggest you can approach Unlock-zone.com and specify the country,locked network of iPhone.You can get the permanent unlock service along with free instructions.
