I have an issue iPhone 3G / Yellowsn0w



I JailBreak my iPhone, and it works well with a Pre-Paid SIM card.
I recently sold it to my friend, and he wants to use a "contract" SIM

in the phone.


When everything works well with the iPhone, 3G, Wifi, Recieve calls,

Send and reciever SMS.

... But every time he tries to click on the phone buttom (to manualy

make a call), the dial pad comes up for 2 seconds, and then it closes

on him!
