Answer 1

All you have to do is have the phone unlocked. Cost to unlock through most independent cellular shops is about $20.00
Once the phone is unlocked, your good to go to make calls and send text messaging. For any internet related service, you will have to manualy change the phone settings to Cingulars. This is easy to do and the settings are listed on Cingulars website
