is there anyway to check how much data you have used on the BB Pearl ?

I know on TMO I can sign in to mytmobile and see... I don't know how on the device itself.

I don't think that you can do it from the device, but on both T-Mobile and Cingular services there is a "My Account" option. On Cingular, it will link you to a webpage where you can check.
