iPhone 4 will not turn on
So, i was playing a app on my iphone 4 and suddenly the screen turns green with white thin lines going through it. DX I did a master reset to turn it off (home and lock button together) and now it will not turn on (completey dead, no sound, no light, no hope) I have charged it all day both from a socket and connected to my computer (in which my computer will no recognise the device). Attempted many times to master reset it whilst connected to the computer and nothing has prevailed. Please help!, I cannot go without my phone for two weeks (if i send it to my local phone store) and there is no apple store near me.
iPhone 4, iOS 5.0.1
