Yeah, you're not gonna hit that 5GB anytime soon.
Mine, on the other hand, says 2411.05 of 10,238,976 MB.
For some reason mine (as I've seen for others) says 1MB for $2. Pretty sure it's meaningless anyway since you hit the throttle long before that anyway. Wonder if the difference means something else...like you've been flagged for high usage or something??? Just thinking here....
I really don't have a clue. My regular data usage has never been more than 250MB in any month so I know that I've never been throttled. Oh well....
