Hey everyone, these forums have been a great source of information, so thanks to everyone for that! I hope you won't mind a stupid non-tech-savvy question.. What will happen if you are driving from a 4g area to a 3g one? Will you drop the call/cancel a download? Will a message pop up that you'd have to respond to? Ideally, the Evo will be able to switch to the slower network without any interruption, but I just hope that will be the case. Similarly, what if you go from 3g to 4g? Will the phone automatically choose the faster newtork when it detects it, or will you have to affirmatively select it? Sorry... I warned you I had some stupid questions!
