Any cellphone guys here that know how to unlock phones to use other carriers sim cards?<br /><br />2 reasons:<br /><br />Friend's parents are going to Italy, they can buy an international sim card and pay buy the minute, but they need an unlocked phone to put it in. They have a nokia 3200<br /><br />...I have Nokia 3120 that I had with ATT, I had to switch to Cingular because of the buyout, I'd love to go back to useing my old phone.
