My service provider offers me unlimited use of Facebook & Twitter through their official apps and mobile sites. On my last bill I noted that they charged it on my regular data plan, but since I have no track the real volume of data for these sites on my BB I'm looking for an app that can monitor data site by site (and maybe app by app).
I already have an app that monitors the volume of data used through wifi and 3G but that is not what I'm looking for.
