i got boned when i upgraded to 4g.... i have 4 gb per month, and haven't come close to going over... back when I had my droid 1 rooted, and was wi-fi tethering (which verizon officially said was not possible) I was using almost 10 gig per month, but now that i got the droid 4, the only real data hogging i do is watching comedy clips when i hit a 4g area and i'm NOT driving (which is rare)
