I recently configured a friends new Blackberry with his email accounts etc and when ever you send him an email he recieves is literally "real -time".

I use Snappermail and and do a typical "send and recieve" then have it disconnect after.

Long question short...If i dont have it disconnect and have Snapper automatically check every 15 minutes will I be billed for the minutes it is connected? OR like T-mobile is the data network on all the time?

Sorry for the wordy question..
