iOS 8 / iPhone 4S MAC Address Masking

Does anybody know if this is possible? I've been looking into it for a bit but can't seem to find anything.

I need to mask my MAC because my school blocked it, so I can't use WiFi there. It's awful and I'd like to see if anyone here can help.

If it's jail broken you can type "nvram wifiaddr=00:00:00:00:00:00" in terminal, replacing the "0's" with whatever you want your new mac to be then reboot device.
To check if it worked you can look under Settings>General>About then look at Wi-Fi Address (that's your mac)
