The same phone as used in the Matrix, for the film they rigged the phone so it slid open on a button, the original phone didn't and you slide it open yourself. 

It is very rare to find one of these unlocked and with a working battery. The battery has been modified with modern lipo cells within the original battery casing so it now charges and holds charge on standby for around 15 hours. 

It is unlocked to all networks apart from Three and as you can see working with my Lebara sim (not included).

It comes with a charger.
