As I understand it, NO carrier will let you use a BlackBerry without the associated BlackBerry data plan, because they've all signed agreements with RIM wherein they agreed to make sure that ALL customers using a BlackBerry were also signed up for a BB data plan.
This is something I heard back in 2005, however, so my info may be out of date. Perhaps things have changed since then, I just can't verify that they have.
not true, nextel is apparently the only one that doesnt allow that, GSM carriers by definition dont usually care what phone is being used by what SIM.

There is nothing stoping someone from buying a blakberry just to use the keyboard for SMS or whatever reason they want it for.. They don't have to get a BB data plan if they don't want to.. Although if you as me it is pretty crazy to have a blackberry without a data plan
correct, the sale of the handset to the carrier is where RIM makes their money, although SOME revenue can be traced to the actual data plan with the carrier, but not much

This needs to be a STICKY
it seems like common sense, im not sure why it needs to be a sticky.
except for CDMA carriers where your ESN (IMEI for GSM) is directly linked to your service account, what phone you're using (keep in mind, below it all a BB is jsut another type of phone) doesnt matter to the carriers.

I think Verchat when it is first installed searches for a network path
Shapeservices apps, search for a network path when the apps are installed
What I have found if you dont have a BB plan is to dump as many Service Books as possible. On the BB 7520 i have 5 Service Books
WAP transport
WAP Browser
Desktop [CICAL]
Desktop [CMIME]
Blackberry Browser
with so few Service Books, this essentially forces all the 3rd part apps to use native TCP.
Eventually I am going to try and hack a 7290 blackberry with a Prepaid GSM sim, if the prepaid packet data prices ever come down
T-Mobile prepaid SIM for sidekick data is like $1/day, thats $30/month
a T-mobile unlimited BB plan is $29.99 a month.
Cingular prepaid SIM packet data is like $0.01/kb ...just based on my recent data usage, that would be $4/day doing the same thing with a Cingular prepaid SIM
if you somehow got a GSM bb to get data without a blackberry plan thats pretty rare. Also, a t-mobile sidekick SIM (of any kind, post or prepaid) will NOT work in a BB. This is because like a BB, a Sidekick plan uses a dedicated APN
