Seriously how much browsing do you plan to do to go over 400MB? My housemate checked his usage over EDGE on his iPhone. Using it pretty much everyday he has used just under 200mb of data since January. I seriously think it would take a lot to go over that. Your usage is not going to be the same as a laptop, and if you use it at home it will be on WiFi. Maybe Matt (houltmac) can give an indication based on his usage.
