My iphone won't let me turn on Wi-Fi?

I have an iphone 4s and i can't turn on my Wi-Fi, when i go on the Wi-Fi tab it is just grey and i can't select it to turn it on. How do i fix this? Please help!

Added (1). I tried reseting the network but it still didn't work, please does anyone know how to fix this?

Is airplane mode on? Turn off factime? Uninstall skype and reinstall skype(if its installed)? Try resetting your network settings? If all these fail please call Apple and setup a time to meet someone at the apple genius bar for repair or replacement. Be aware there are costs to this if you did not purchase applecare+.

Thank you… Works great now!
