I just downloaded PDANet and am successfully using internet with my Droid tethered. My concern is, if I use it only for browing the web (including youtube, but no bittorrent download or any massive data transfer), and say I do it for 4-5 hours a day, 7 days a week. Will this hit my data cap for my 29.99 plan? I know they said the data is unlimited, but will this kind of usage alert them in any way? Am I also likely to incur any unexpected charges? I'm not roaming, just using it from my home.
