Im trying to get my friend to try out Elementary OS Luna (based on Ubuntu 12.04) but the problem at our school is that the wifi dosen't support Linux, only Windows, Mac and Android. Therefor I get my internet by connecting to wifi from my phone (Galaxy S II) and then thethering it to my computer. Can I do the same with an iPhone 5?

The same should work with an iPhone. Just enable WiFi tethering in settings, then look that WiFi in Ubuntu and enter the connection password. (By the way, you should be able to connect to your school network in the same manner.)
