Sony Xperia S 32GB - Boxed - o2 (Tesco) *

Sony Xperia S 32GB on o2 (works on Tesco). Fully boxed with all bits. Full working order with original software (no rooting) and in great condition. Looking for 200 ono cash or swap for iPhone 4 or Nokia Lumia 800. (Either need to be on Orange/T-Mobile or unlocked) Thanks, Kris.
