My iPhone 5 just stopped working now not visible with iTunes
I have had the iPhone 5 for a few weeks, tonight I was recieving a call, as I went to answer it the slide bar locked half way accross and the phone locked up. It then turned its self off and now won't start up again, I have connected it to my iMac to see if iTunes can resotre it but iTunes doesnt even recogonise anything is plugged in.
Whats my best steps from here?
Things to try...
Or is it back to the store when they open tomorrow?
