On the other hand, if you *didn't* have unlimited data you would have been hit with huge overages.
Since it was an accident that you left your phone downloading podcasts off wifi do you really think this will be an ongoing issue?
Right now the only decent carrier offering true unlimited is T-mobile--and their coverage varies *greatly* by location.
On occasion when I go over my speeds slow to 500kbps -- which I've found is still usable for everything except video streaming. Perhaps your area will get the higher throttled speeds at some point.
