How can I determine if my HD2 is using my Carriers 3G internet or my WiFi? Basicly, i'm from Australia, and our ISPs (Namely Telstra) offer extremely limited usage amounts for every form of internet use. I would like to use my HD2 freely on the internet whilst at home, without the fear that it is consuming my precious 100MiB per month, even though my plan is $85 a month. Please inform me of how I can know for sure if the HD2 is using Wifi - does it passively route all connections through it when connected? I'm not very experienced with the phone, only bought a few days ago. Thanks alot.
