I managed to smash the screen of my iphone. O2 are sending me a replacement tomorrow but will I be able to transfer all my current items (eg SMS ,phone numbers, music, apps etc) from one to the other easily? I will still be using the same SIM card but am worried that I will lose all my information, some of which is very important. I have backed up my old phone on iTunes but is there any way to check that everything has been backed up fully or will this just automatically be completely done? Any help will be greatly appreciated!
