I've just received my brand new Galaxy S2 today. I've found the manual on Samsung's website and am slowly working my way through it. What's confusing me is the internet. I'm going to connect to my home Wi-Fi (once I dig out the tatty piece of paper I've got the password written down on.) Will that mean that whenever I'm in reach of my home network it will use that automatically? And elsewhere will it just use the MB that come with my contract? Does this even make sense?
