A friend has a Palm Treo 600, which he bought secondhand off Trademe. Being based in Wellington, I cant see the phone for myself, and I have never actually owned a Palm OS unit with a phone component.

Step by step, how does he change the callback number for SMS? At the moment, when he texts someone, the see his number as being the sender - but if they hit 'reply' it goes to the old owner of the phone.

TIA

Big Tony.
