Iphone 4s - 16g, white on 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. :) IF you have any questions feel free to ask.
