Hi so i have a t-mobile iPhone 3g and i went to update the software from 2.1 to 2.2 i did it through iTunes and once the update was complete my phone kept saying i had no service so i chose to restore my phone to the original setting i did that and my phone shut off and turned back on but now it is saying that No SIM card is installed when there really is a sim card in the phone i use the gevey sim installer so i can use my iPhone with t-mobile does anybody know what i can do to fix this?

i'm quite sure if you use a sim card unlock for the iPhone 3g that it DOES NOT work with 2.2. unfortunately you are SOL and need to downgrade to 2.1, even that i am not sure will help you as your baseband has been upgraded. you could be in for a bit of a wait until someone on the software end updates this.
