This is a surplus upgrade phone. It has only been used for about 3 weeks, and is in excellent condition (minus a small scratch).
It is locked to T-mobile, but can apparently be unlocked for £3.99: http://www.mobile-unlock-codes.co.uk/?gclid=CMvtzob30aMCFWMA4wodEV3-HA
Comes with box, manual, battery, charger, etc.
Am based in London, and would be happy to do the exchange in zone 1. Happy to post as well, of course.
Let me know if you have any questions.
