I Phone 4 Black 16GB *

I am selling my I phone 4, the phone is black and is 16GB. The handset is locked on T mobile, I purchased the handset from T Mobile, the handset is 18 months old and in immaculate condition, I do not have the box, however, comes complete with charger, headphone and receipt, which is often required for insuring the phone. Please note, the handset is NOT UNLOCKED. Please no offers and would need to pay cash on collection. Would need to collect from Kings Cross.
