I’m distracted by other news right now, but Jeff Shafer from Sprint sent me the following about my earlier Treo 650/Bluetooth posts:

I know there was some discussion among your readers that Sprint prohibits
the use of Treos and other devices as modems, and as I mentioned, Sprint
does not “stand in the way” of our customers who choose to use their
devices in this manner.

However, to be perfectly clear and avoid any confusion among our
customers and your readers, there are limitations to using devices as
modems in the unlimited Sprint Vision pricing plans.  Customers who
choose to use their devices in this manner may be required to select a
different pricing plan.  I do not have the details on exactly how the
alternative pricing works (these would be available from a Sprint PCS
service representative), but these are plans that are in existence now
and are designed to help customers who have needs other than for the
standard unlimited approach.
