Iphone 4S 16gb in white (o2) ?

Phone been in use about 5 month. been bought from O2. In working condition, but have few problems. As it was been accidently in a water, rear camera stoped working, just need to replace (£25 on ebay) and sometimes goes down hearing dinamic, probably wires not conected properly, but if you press on top of the phone its goes back to live. :) Phone goes in original box with charger and earphones.
