then all of your data for that app (Google Earth, telnet/ssh, Berry411, etc.) will go thorugh your BES. It's considered BlackBerry data and not WAP-style data, and you have unlimited BlackBerry data. All your emails and BlackBerry Browser (perhaps not Carrier Browser) traffic will be considered BlackBerry data too.
No BES? Then you'll either have to deal with metered usage or find a hosted BES service. Or possibly see if there is an unlimited non-BlackBerry data plan you can tack on without breaking the BlackBerry data.
SMS/MMS is still going to draw from a message bucket or pay-as-you-go.
If someone feels I'm wrong here, I'd love to chat about it further.
Pick two CSRs at random from Cingular and, chances are, one of them will think you're wrong.
Thanks for the info; basically, what you're saying makes sense in theory. If I pay for unlimited BB data then, if I use BB data, I don't pay any more. Otherwise, I do. Problem is, it's difficult to define "BB data" as well as determine which apps use it. For example, Cingular's TOS indicates that unlimited BB data INCLUDES "Internet browsing" (their term). Is that WAP, HTML only, or what? Also, for example, does bbWeather use the BB APN or not, and if the latter, can it use MDS? I believe blackberry411 has an MDS option, don't know about bbWeather.
I understand this subject has been beaten to death and there simply IS no answer (except, as in "1984", what Cingular WANTS it to be
). So if one chooses to use Cingular, for whatever reason, then they're going to have to live with the ambiguity. This leaves aside the so-called new Cingular "BB Tethering Plan" I've heard about, since even if that exists it's $75 and probably still has loads of loopholes.
Again, thanks for the post.
