location: apple.com - date: December 5, 2011
Hi all  The girlfriend dropped her Iphone4 today and broke the rear cover I called the phone insurance and they are replacing it tomorrow. so i needed to backup her phone and get it ready to be replaced The phone was running IOS5 with no probs. i had no trouble updating it on the original release date either So Itunes told me there was a new update . 5.1 . i transfered purchases and backed the phone up and set it to download the new update.. i came back to find an error message :Restore error 1602 Now the phone is stuck with a picture of the usb lead and that i should connect to i tunes  The (Win7) pc no longer recognises the phone either .. I searched lots of forums and tried lots of diferent way to restart the phone . none work . Things like : turning off iphone with top power button and home button
