All of a sudden my lock/sleep button as jammed! I have read up a lot on this for the past few hours and seems quite a common problem, I have issued an appointment at Manchester Apple Store tomorrow for a fix/replacement. As anyone else come across this problem? Also, my phone is in PERFECT condition, i mean MINT! If it needs replacing do they give you a brand new phone? Not some scratched rubbish? Never had to do this before.
