IPhone 4S doesn't turn on/off Wi-Fi?

I got my iPhone 4S recently. All of a sudden, my iPhone doesn't turn on. I keep pressing the home and power button, but it doesn't power on until I hold both buttons (reboot). Once it finally turns on, the Wi-Fi button is shaded. It says that it's off and I'm not able to turn on the Wi-Fi. I have to reboot the device again for it to work. How come this happens? What can I do to fix it?

What MP3/MP4 Player is Best For Me?

Hi, I recently sold my old iPod Touch 4th generation 32 g because I bought the 16G iPhone 5. This new iPhone can't hold my whole song library (My old iTouch barely did) so I'm in need of a new MP3 or MP4 player. It needs to have: Lots of memory, Be able to use control talk, have a headphone jack (obviously), and a screen. I would like it to be able to play video as well but I can sacrifice that for a good MP3 player, also I would like it to have an arm strap accessory for exercising but again, I can sacrifice that if the player is really good. My target price range is $0-$300 but I can go higher if the product is really good. The MP4 player I've been thinking of buying is the iPod classic, but what do you think?
