Do you have a blackberry data plan, a general mobile data plan, or no data plan?
What data applications are you using? Are they all able to use wifi, and are they set to use wifi? Perhaps they are using carrier data over the mobile network?
i have no data plan, i just connect wifi at cafe. and i just open the application " BROWSER" from the menu.
