Just got my Iphone and LOVIN it!! However it doesnt connect to the internet other than the wireless router at home, eg, i want to download an app, it wont let me because it tells me I need to connect to a wireless network, so I have to do that instead of connecting through my sim, but how can I connect through my sim.

I know Im babbling but you get the gist? I hope

HEEEEELLLLPPPPPPPP MMMMMEEEEEEEEEEEEEEEE!!!!!
