HI,

I phone an old iphone 3g, which  i'd like to use some times.

When I switch it on, it's said I heve to connect to itunes.

I did, then on the computer, the message says I have the wrong sim card.

So It needs to be unblock to allow a different network.

I have no idea what was the previous network, also same form the firmware or anything, as I can't go in the settings of the phone.

Question: Where can I go to unblock it in Geneva or around?

Thanks for your help

Kevin
