Can't Sync on Itunes after unlock/Jailbreak SIM not supported

[DrJB]

Hey everyone happy new year I had to use blacksnow and blackrain to unlock/jailbreak my phone again , but this time it's really weird it actually says my carrier name and I can make calls and everything, but when I hook it up to itunes to sync it it says the following:

THIS SIM INSERTED IN THIS IPHONE DOES NOT APPEAR TO SUPPORTED

I don't know how this happened and it has never happened to me before anyone have any ideas why and how to fix it? So I can sync my phone with itunes. Thanks

I had the same issue... I don't know what is causing it or how to fix it. I do have a work-around. If you have an AT&T Sim Card and insert it - then it will allow you to access your iPhone through iTunes...
I was even able to change back to the T-Mobile sim card and it still worked fine within iTunes... so if you have access to an AT&T Sim Card you may want to try that.
Good luck!

One more thing... it's almost like it was a periodic check or something... it has worked for 3 days now with the T-Mobile Sim Card and not come up with the non-supported sim card error.

Also, just so you know:

Model: (MB717LL) 3GS Black
Version: 3.1.2 (7D11)
Carrier 5.0
Modem Firmware: 05.11.07

Jaibreak: BlackRa1n
Unlock: BlackSn0w
