Assuming that the 4G hotspot is going to be an extra fee, do you think it will automatically switch between 3G and 4G networks if you are on a road trip? The main reason I want the phone is for the 4G hotspot idea for when I'm out and about with my laptop. If I'm a passenger, I can use it. Or my gfriend can use the WiFi on her Itouch for long road trips. Will it automatically switch between 3G and 4G? How is this currently handled by 3G hotspot apps? I've never used one before. I'm a blackberry user, and blackberries suck now compared to other phones.
