iPhone 4 32GB - Excellent condition in box -

I am selling my iPhone 4 32 GB which comes in a box, charger and headphones. The phone still has its back and front protective screen therefore has no scratches. Around the sides are some slight surface marks due to being in a plastic case. The phone has no other damage and has been very well cared for. Was purchased part of my t-mobile upgrade and has original receipt. Not sure if it is unlocked to other networks. Any questions, please ask. 07929 921941
