Hi there, my wife has an unlocked iphone first gen. shes on tmobile and its worked fine. she recently synced it and accidentally updated to software.

All still worked fine. Now shes getting No Sim Card error. How can we fix this? thanks!

Tell her never to accidentally try to upgrade the software on a software unlocked iphone or it will lock up again.
Most likelly you will have to rejailbreak and unlock it again.
