I know here all of our BIS plans are unlimited on-device browsing and anything that runs through BIS such as BBM voice, IM+ Skype Voice, etc are also free and unlimited.
So now I'm going to chew through my 1GB cap easily like when I upload a good couple hundred 5MB photos to Facebook which is normally free on BIS as its under the 8MB limit.
We don't pay a cent for BIS, its included in plans and prepaid at no extra cost.
Thanks BlackBerry. You're also going to lose a lot of third world customers as BIS is the rage there as its cheap and normally unlimited for a fixed fee.
