So i want to buy an unlocked Blackberry 9700 or curve 8900 from ebay, and then buy a prepaid card sim.
1. Would i need to activate the sim card on the phone it comes with and then put it into my blackberry?
2. What service provider for prepaid/pay as you go should i get? att, verizon, tmobile?
3. Will my apps and services (internet) be off, or can i still use it?

Thanks soooo much!! <3
