SAMSUNG S3 WHITE UNLOCKED CASH - OR SWAP HTC ONEX .

I have a Samsung Galaxy S3 White 16GB Unlocked (No box or accessories just phone in perfect condition no marks). Why is there no box and accessories??!! Because I broke with my girlfriend and I was paying for phone and she just give the phone back on spot.... There is no scam the phone works perfect all kind of test accepted. The price is 275 GBP I want more a SWAP with an HTC ONE X Unlocked in Box. I can PAY a small Difference. Can meet today for both cases. Thanks
