Yesterday night my iphone 4 completely cut off, i left it on the charger over night hoping it'll come on, it didn't, i have tried pressing the home button and top button for 10 secs but it didn't work either, I also plugged it to itunes but it says error 1600. What else ca i do to get my phone back working. I called the itunes store ad they said it would cost $400 for a new phone
