HTC RADAR 7.5 WINDOWS PHONE WITH 8GB MEMORY +

Hi There, I am selling my HTC Radar mobile phone which has been unlocked to work on any network., I have only had the phone for 5 months., it still looks new, I still have the original box and the headphones are still sealed in their original packaging, the phone has always had a screen protector and been in a hard case cover to prevent any scratches etc., I have included 3 hard case covers in Blue, Red and Purple and the charger. This is a 7.5 Windows Phone with an 8GB of memory its a great mobile phone, I got the chance of an iPhone therefore, I decided to sell this one. I purchased it from the carphone warehouse, I am assuming it will have a 12 month manufactures warranty, therefore I reckon there is still roughly 6 to 7 months remaining. However am not sure how that works after selling on again.? Thanks for looking.
