Sim free Samsung S2 *

Hi im looking to sell my Samsung S2 details....... Fully boxed with everything apart from headphones i used them. Phone was bought sim free so no need to worry about getting someones contract phone that will get blocked! Screen protector been on since new so the screen hasnt got a mark. Rear 2 stage cover inside rubber and outside hard plastic so not a mark on the phone. It is as new. 32GB memory card included making the phone 48gb worth of storage. The phone software is all up to date running the newest android software out for it. Never had a problem with the phone just looking for a change so im open to swaps but no blackberrys. Must be on o2 or unlocked mines is sim free so should take any sim ive had o2 and vodaphone and both worked. Im open to offer but would prefer swap if your interested send me a offer? Thanks
