Hello guys! Have a Sony Xperia J and want to sale it, because want to buy a Z model. What do you think? How much should I ask for my phone? It is unlocked and one year old. Don't know for sure what is the market price for this phone. Also, I want to get an unlocked Sony Xperia Z but which is not ollder than 6 months and no scratches! Do you think 200 $ is a good bid? Thanks a lot!
