I have an iPhone 3G that is jailbroken and unlocked. I used it on Fido network and synced with my computer with no problems at all.

I recently gave it to my father. He put a ROGERS sim card in it and is using it on ROGERS network. The phone works just fine. I left all the settings in it the way they were when I used it with FIDO though.

When he connects it to his itunes on his computer, he gets the error: "The SIM card inserted in this iPhone does not appear to be supported"

Itunes recognizes the iPhone, yet I do not get about page with the name and number of the iPhone and no other tabs to control the sync options.

What do I need to do in order to fix this problem?

Please help.
