I rarely use over 2GB a month on my iPhone4, I'm thinking of opening a line on Verizon before the unlimited ends to lock myself into it for 4G(that's the way I understand it). My question for those using 4G on Android, have you seen your data usage jump up vs 3G? I'm not 100% on how this could happen, but I've read some posts that since the data speeds are higher you will be using more data. I really not sure about this as if you load a page on say a Thunderbolt while on 3G vs 4G wouldn't the data used to load that page be the same except for the speed in which it loads. If you're not seeing and increase in the amount of data being used then I see no reason to sign up now as unlimited wouldn't mean much to me unless this is going to happen.
