It used to be that BB email and browsing used the BB APN and BIS to get to data (and thus require the BB service enabled). Other apps used the general GPRS APN (which you had to configure in TCP settings correctly to make the app communicate ok)

It seems most apps now (only?) use the BB APN/BIS route (and many aren't confurable manually)

So what about Google Maps or Gooogle's Gmail app, for example? Do they work if I *don't* have a BB "service". or if I kill the TCP settings?

For all the common 3rd party apps I'm trying to work out:

A. What happens if I don't have a BB service on the device

B. What happens the other way round - if I have a BB service and pay by the KB if the app uses the general GPRS APN

Anyone got a list of how the different apps work?

If you don't have BIS/BES, Google Maps, Gmail, and some other programs will still work. Those just require a data plan, but not necessarily a BlackBerry one.

So if I DO have a BIS plan will Google Maps, Gmail, and some other programs use this in preference? Or will they use the general GPRS APN ('data plan') for which I may be charged by the KB?

Why do you have two data plans. If you have BIS, then you do not need any other data plan. But if you have a generic data plan, only browsers such as opera mini and third party apps will work. You don't need two data plans.

If you have BIS, it will use BIS. It won't switch you over to GPRS and pay-as-u-go.
