I might try that -- Is there any way to automatically keep track of a
summary?

I don't want to have to add up the numbers manually, I'm much too lazy
for that (and I use GPRS a lot, I have AIM open constantly, and use
email a fair amount)

I signed up for a package large enough to cover the amount of data I was
transferring on my old iDEN phone (which did keep track of the KBs
transferred), but since I'm using IMAP rather then HTTP to transfer the
mail it's hard to guesstimate what my KB usage will be.

Worst case, I'll eat a huge KB bill one month and upgrade my package and
call it a learning experience.

Thanks!

I'm only seeing "Last Call", "Dialed Calls", "Received Calls", "All
Calls", and "Lifetime", all of which are minutes, none are in KB.

That would seem to be the logical place though, and my years-old
Motorola iDEN phones all showed the KB transferred under the call
timers, so it's not a concept that Motorola is unfamiliar with :)
