After spending a couple of hours reading how to do it, I jailbroke and unlocked an old iPhone 3G recently. The thing worked like a champ when I transferred theSTC SIM card from Nokia N72 which finally gave up the ghost this week.
So now a question arises. Is possible to buy a SIM card that will permit both phone and data that can be used in this iPhone.
The lad at the local electronic shop I visited yesterday told me that such SIM cards are only sold packaged with a new smart phone. According to him combined phone and data SIM cards aren't available a la carte
Any illumination on the matter would be much appreciated.
