Black 

AT&T (I am not sure if it is "unlocked" but it was originally used on AT&T's Network)

256MB Internal Storage, but can take a MicroSD and MicroSDHC card to expand it's storage

This phone is currently factory reset and in working condition. There is some wear on the phone, which you can see in the photos. The phone is being sold AS-IS.

The phone does have a SIM card, but it does not have a MicroSD storage card.
