iPhone 4 with original receipt .

I have an iPhone 4 (16GB) for sale. I bought the phone from T-Mobile and still have the original receipt. The phone is in immaculate condition, it does not even have a single scratch. It has been well looked after and has had a screen protector and been in a case since day 1. It includes the box and all accessories. However, does not include the headphones due to hygiene reasons. The phone is locked to T-Mobile. The reason for sale is that I have the new iPhone so it is not required anymore. Please do not hesitate to contact me regarding any queries. Many thanks
