Need some help please -- I'm looking at a blackberry tomorrow that's supposedly new and i'm totally unfamiliar with them. I have a few questions: 1. How would I check to make sure it was never activated? 2. Where does it say the model #? 3. What things can I check to see how long it's been used? (Minutes active recorded or anything?) 4. Anyone have any advice of thigns to look for before buying it. I'm buying it form a person, not a store. Person says it's brand new basically.
