    I updated to iOS 4.2 today on my iPhone 4 and everything was going okay. I was just played a game, exited out, locked and tried to unlock (out of habit), and it won't turn back on. It had at least 40% of battery life left.

    And now I've just plugged it into the Mac and it doesn't detect it. :eek:.

    This actually happened to me the other day. After a few hours the battery will die and the phone will be usable again. It just seems like a proximity sensor problem.

    You can test this by calling your phone and it will ring as if the phone is on the main screen, and not just dead.

    Nope, and it won't charge now either. I'm trying the wall charger too.

    And it's still dead. Tried plugging it into my G5 too.

    I locked my Iphone 4 last night after the OS 4.2.1 upgrade and like yours it is dead today. I had 80%+ battery last night. Plugged into Macbook Pro - still dead. Plugged into wall outlet - still dead. Held the on button 2 mins - nothing. Tried to phone it from land line - went straight to iPhone voice mail.

    Solution

    I tried this and it worked:

    - 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

    I then tested it by pressing the on/off button to kill the screen, and pressing the on/off button again brought the screen back.

    Happy happy, so far.
