Have you been billed yet since you have been using the TCP/IP APN data?
I am using the BB Maps (not Google Maps or other 3rd party app) rerouted through the TMo APN through an application called Aerize WifiX, which I luckily have the license for (and is not sold anymore) and which can reroute applications to access the appropriate hosts through Wifi and/or TCP (applications that otherwise can't be used without BIS/BES). Not all applications work though, even after adding the hosts and chaning the connection type through it.
I haven't been billed (even though I don't have a data plan) and have been using this for something more than 2 months.
You can find a lot more details on this on Google, methinks.
