I will admit it. I own a Blackberry Pearl, but I bought it used through my work. There for I did not sign up for the Blackberry Plan or any form of data for my account. I noticed a $2.17 charge on my account for data usage. We have unlimted Pics, Texts, Videos and the such on our account.
My question is, just because I'm using a blackberry, I shouldn't be getting wacked any bit for data right?
I suspect that your best option is to talk to AT&T and see what these charges are for and, if you dispute the legitimacy of the charges because of other characteristics of your plan, work with them to resolve it. We simply don't know enough about the details of your plan or what you might have done -- clicked on the brower while the BB was in your pocket, for example -- that may have caused these charges. Or it could be a billing error -- they do happen sometimes.
