My iPhone 4 16gb rattles really badly which I can live with, the whole thing appears to move internally and the volume and power keys move around very freely compared to the wife's. Also to top it if you press on the sides of the front screen it causes the screen to discolour like its touching the actual inside screen, a bit like when you touch a LCD screen. The phone works fine so I will live with it especially as its now 15 months old so out of warranty but Im just wondering if anybody else has or had a similar problem? Like I say it works, I can only presume I must have dropped it to often, but there is no external damage? I suspect it would cost a fortune to be fixed so when I sell it at the end of the year (end of contract) I will have to advertise it as broken.
