I took the phone and the chargers to at&t and they told me that the phone needs a new battery and that the current battery may not be working. I aked them if they had a battery they could test the phone with and they said they could not do that. I was also told that the phone has WiFi.
Having said that this phone is being auctioned as it is. I am not making any of the above claims for this auction. Thank you for your comment.
It took the battery out and just below it there is a white label with a lot of letters and numbers, but next to the work Blackberry are the numbers 8310. I assume that is the model number. I hope this helps.
