hello

i've have a question as my web research didn't bring up a solution.

I have iPhone 3G 8GB v2.1, VirginSIM, iTunes 8.0, Windows Vista.

My iPhone was activated with the original SIM card. Now I'm using it with another SIM card together with the VirginSIM.

Everything works fine. But not with iTunes. I get the message that the SIM is not valid. (flight modus is not the solution for me as I don't want to reboot my phone all the time).

I've read that I have to reactivate the iPhone. but I could find how to do that. I've read something about lockdownd, SSH, etc.

Does anyone know how to do this or a good HOWTO explanation?

thanks a lot in advance

Cheers
