    Dear all,
    what to do when your iPhone4 updated to iOS 4.2.1 doesn't work anymore?

    I gently posed the iPhone on the table, as always.
    The iPhone was on and locked and the battery far from being drained.
    A few moments later, I took the phone to check a number and I discovered that the screen was not turning on, no matter which button I was pressing...
    It's like it's been switched off, but it doesn't turn on if I press the power button...
    If I plug the USB cable to charge it, nothing happens...
    If I press any other button (even for a long time), nothing happens...

    What happened? What can I do to switch it on?
    Is the recent upgrade's fault? Am I the only one?

    Thank you all in advance,

    You're not the only one with this problem, try this:

    - started iTunes
    - connected iPhone to laptop
    - pressed Home button and On/Off button for about 10 seconds until I saw the Apple logo
    - it rebooted and sync'd just fine with iTunes

    Hi Stein,
    thank you for your suggestions!

    I had read similar thread, but nothing really helped...

    I just figure out how to solve the problem: I pressed Power button and Home button together for something like 45 seconds... so don't give up after 10 seconds like I did before, keep on pressing...

    I was happy to upgrade because of the alarm bug, but this new one is even worst!

    By the way, does anyone noticed that fade transitions from a screen to another are no more fluid as they were used to be?

    Have a nice day to everyone,

    Thank you, thank you, thank you.

    You just saved me a trip to San Antonio (the nearest city with an Apple store), to get my iPhone fixed.

    Thank you again
