In speaking with AT&T today about the Captivate's latest update, we learned something interesting that we thought we'd pass on: data isn't deducted from your bucket for over-the-air firmware updates. That's important since updates can climb into triple-digit megabytes -- and if you're on one of AT&T's newer DataPlus or DataPro plans, you really don't have any data to squander. Obviously, this isn't going to take away the sting of unlimited data's untimely demise -- but the next time you get a notification on your phone that some shiny, new system update is available, don't hesitate to kick it off (unless you're in some foreign country, we suppose, in which case you could very well be bankrupted).
