Samsung Galaxy Nexus, SWAP L@@K !

I have a 2 week old Samsung Galaxy Nexus all boxed up with charger, usb and good quality sennheiser headphones. Mint condition, It is factory unlocked and was bought from 3 store 3 weeks ago for £500, Also comes with a few screen protectors and a case. The phone is on a custom rom which you can put back to the standard rom but this rom is supposed to increase the phones performance . There is a scratch on the screen that is noticable but may be able to buff out or remove with scratch remover but dont know whether it will or not. I want to swap for another top smart phone like a Iphone 4S or Something similar and will except offers with cash on top aswell as a Decent phone. Email with offers. Also will sell for £300 because of the scratch otherwise i would sell alot dearer. These phones are going for £380 and above on ebay so dont offer me rubbish phones as this is on the latest Android 4.0 and dual core etc.
