Yeah exactly. I use my phone like this (Wifi tethering on Windows Phone) so I can use my iPod and laptop anywhere but it's a real drain on battery life and Vodafone's unlimited internet is rly about 500MBs. One lunch time at college I had 7 iPod Touch's connect, a few people watching YouTube vids and downloading stuff from iTunes and Vodafone hurriedly informed me I was about to use my 500MBs :/
