Hi, Would like to trade my Galaxy S2 16GB - unlocked and unbranded for a mint iPhone 4. (White would be nice but black is also good) GS2 is completely unmarked and in 100% mint condition with box and all accessories. It also comes with a 8GB micro sd card. I would expect the iPhone to be in a similar condition with no marks etc. I'm located in Northampton, but happy to drive up to an hour or so to meet and do the swap. No posting of devices as it's far to risky for both parties in involved. Reason for sale: Fancied a change to Android, but if I'm honest I think I prefer the simplicity of iOS for my needs. Pictures available on request. Andy. Edit: Forgot to add. Needs to be unlocked or working on o2.
