iphone wont turn on

Have you tried a reset by pressing and holding the sleep/wake button and the home button for 10-15 seconds until the Apple logo appears, ignore the red slider. Then turn back on. You won't lose any data doing the reset.

Thanks Huntress, that worked for me.

You're welcome.

Didn't work out for me. Anything else I can try?

Nevermind. This fixed my problem. 3rd option was a god sent.

Thanks for this post and you response Huntress. This is the second time my wife's iPhone 4S did this since we got in December. Do you know why it happens? Is there a firmware update for this issue? I have an iPhone 4 and I have never had this issue.

Glad it worked. The reason is often as simple as the iPhone occasionally needs a reboot much like a PC does sometimes. If you feel your iPhone requires frequent resets I would make an appointment at the Genius Bar at the Apple Store. There have been a couple of software updates since December so it might be useful to ensure that's up to date.

Huntress I need your help big time! my phone will not turn on it wont show anything when i plug it in and it will not show the logo when i try to hold the buttons
