After IOS 7 my iphone apps won't open and it isn't working?

So just a couple of hours ago my iPhone started acting all weird.none of the apps would open at all. When i turned my iPhone off and clicked the power button, instead of seeing the lock screen it just goes straight to the home menu.basically the whole phone is useless right now. Its been fine since i updated it, but it just started this.

You might want to try restoring your phone. When you connect it to your computer, you should have a Restore option to reload the iOS and your apps, music, etc. During the restore you should have 2 options -- one to restore the device from backup and one to set up the device as new. The "restore from backup" option will restore all your apps, music, settings, etc. But there's a chance that it will also bring back whatever the problem is.

The "set up as new" option will basically wipe out the device and reload the iOS. You can set it back up the same as before and reload your apps, music, photos, etc.

Make sure you back up your device before restoring it, including everything you want to keep from the Camera Roll as this section isn't backed up by iTunes.

Turn it off and then on. You can try several times. If many times are all to no avail, you may need to restore your iPhone to factory settings.
