Hey! I got my new Iphone 3g today and i installed itunes etc. Then iwanted to connect with internet. I activated Wi-Fi and i was in the internet. But i wondered, wheter its from the W-lan or from the Iphone. If it´s from the iphone it´ll cost me much money. Then i shutted my internet off and tried to go to itnernet with my iphone again. And i could surf in the internet. So it has to be the iphone internet. But how can i deactivate the iphone internet ? I don´t want to go online with iphone internet, because it costs me . Please help.
