phone switch off and a red apple came on screen

If you hit this problem it does not mean your iPhone is "bricked". You can resolve it by performing a complete restore on the iPhone by following these instructions:

• Press and hold Sleep/Wake and Home buttons until the iPhone resets.
• When the Apple Logo appears release Sleep/Wake, but do not release the Home button until you see the prompt to "Connect to iTunes".
• Restore your iPhone, but the trick here is restore it not from the backup (as it could be corrupted and very unreliable) but restore as a New iPhone (though the downside is that this process could take a long time for backup and syncing; depending on the applications you have downloaded).
• One of the recommendation to prevent this problem is to update iPhone apps one at a time instead of using "Update All" and avoid doing anything else on your iPhone while the update process is taking place.

Some iPhone users have reported that they have not been able to plug their iPhone to the computer to sync with iTunes after upgrading to iPhone firmware 2.0.1 and instead hit the "Apple logo screen of death" problem. In case you are facing this problem, you need to put your iPhone into Recovery mode as follows:

• Press and hold the Home button while reconnecting the USB cable. This should kick the iPhone out of its Apple logo screen.
• Let go of the Home button when "Connect to iTunes" shows up on the screen. iTunes will inform you that it’s in the process of recovering the iPhone.

Please do note that restoring your iPhone as a New iPhone would result in losing your personal data such as text messages, notes, contacts, etc so you will have to manually sync them. It would also remove your application specific data so if you have already played many levels of an iPhone game, restoring the iPhone as new will result in you having to start all over again.
