I have an iPhone 4 and for the past 24 hours it will not turn on. I have tried to charge it and it will not do anything. I plugged it into the computer and it will not even sense that anything is plugged in. I know that it is on because the sound slider on the side will not vibrate when I switch it. To make matters worse, my top button hasn't worked for a while and I don't know what to do from here!
Plug your i device into your computer and open itunes.
Then press and hold both buttons for 10 seconds then let go of the power button but remain holding the home button for an additional 20 seconds
After that itunes should then say your phone is in recovery mode
the device will do nothing but Itunes will take you thru its recovery.
Let me know if this works
