I have a Nexus 5 for sale from T-Mobile. I bet it can be opened for other lugs, but I do not do that. There is a fracture on the bottom best part of the screen, for this reason the lowered price, however it is hardly noticeable when using the phone. I bought it in February, however switched to Verizon just recently. I have the original box, charger, and screen protector(one on and another if needed for changing). It is 16gb and black (as seen in image). I would only be wiling to trade for a Microsoft Surface RT. Please do not be reluctant to ask if you have any concerns.
Thanks!
