Try a hard reboot first - hold both home and power for around 10 seconds, until the Apple logo appears.
It does not delete anything, just forces a proper "clean boot".

If that does not work, a reflash may fix it; they occasionally get problems due to a corrupted update, like any computer.

Back it up via itunes first, if there's anything you want to keep.

Then press both home & power buttons, but release the power button after 8 seconds and continue to hold the power button (for about another 20 seconds)
Hold until you see a "Connect to itunes" graphic or itunes detects the phone as being in DFU mode.

itunes should detect it as needing the operating system reloading. It will download the correct operating system and reinstall the whole phone, putting it back to "as new" state with the latest OS, all in one go.
(See the link below for more details).

When its finished, you can activate it as a new phone or put your backup on it during activation to make it as it was before, with your apps and data etc.

If it still acts up, it may have hardware faults or be water damaged etc.

So you've just come into possession of an iPhone that doesn't work, and you can't return it to where it came from? Maybe you should try buying one next time!

For the record rebooting is just another term for restarting.

You could try restoring it through iTunes or at least contact Apple about it.

Don't know any reason why it "can't be taken back"

  • Wi-Fi keeps shutting off automatically on iPhone? I recently purchased an iPhone 4S and ever since I connected it to my Wi-Fi home network it has been disconnecting off of the Wi-Fi and using my 3G. The Wi-Fi works great on my other devices, and I have to keep manually going to settings to connect it. Please tell me what to do to fix this issue and let it stay on the network until I manually disconnect it. 10 POINTS for the correct answer
  • My PC keeps shutting down/ restarting on its own Ok, so my computer does not have internet right at the moment, but that is not the problem. Whenever I plug my iphone into the computer and open iTunes, it shuts down in between 10-20 seconds. Then it restarts again! Please keep your solution simple, as that is mostly why I came here.
  • My iPhone keeps turning on and off like it turns on and off. Can someone tell me? Okay tbms it turns on and off on and off and then sometimes it shows a red screen for a few seconds then off again and dies out. It's not the battery because I got that changed thinking that it was the cause and it wasn't. So is there anything someone can help me with? The repair guy tried restoring it through iTunes he said it didn't work either it just won't come on it doesn't go pass the Apple logo before shutting off and on again and dying out
  • My iphone keeps shutting off? I have an iphone 3g. The only way it will stay on if its on the charger or if its off the charger it must be playing music to stay on, but as soon as the music stops playing it will turn itself off and then start blinking the apple. The apple will come up and then go away and then come back. This just started happening lastnight, how can i fix it?
