Can't Handle Data Rollover Plans – DataMan Pro Review

I sometimes roll over 1 to 2 gigs of unused data on my 3-gig-per-month AT&T plan. The rolled-over data is available for use during only the next month, but rolling over 2 gigs means that I will have 5 gigs of data instead of 3 gigs to use during that month. DataMan cannot process rollevers and so I have to look up the rollover amount on my bill every month and manually adjust my data cap for the current month. DataMan Support advised me that they are "looking into my feature request" to fix the problem.
