I'm going to chime in here again on this:

Here in the US, getting pre-paid voice service via a T-Mobile sim is no
problem exactly as Mary illustrates.

The problem is getting pre-paid GPRS access to anywhere on the net OUTSIDE
of T-Mobile's silly "T-Zones" walled garden.

~90% of the amazing applications that will be written for the OpenMoko/Neo
platform will involve pulling and pushing data to and from your handset via

T-Mobile or Sprint(??) must be induced to offer a prepaid GPRS service if
the OpenMoko/Neo platform is to be as fully successful as possible.

If this prepaid GPRS access fails to materialize, has anyone done any work
on creating a working cellular voice modem that could communicate via a
personal dialup gateway at home?

My experience here was almost the same as yours -- the difference
being that all the plans I saw had a bottom-end phone that they'd give
you for "free" (in quotes since the plan subsidizes the phone).  They
told me I couldn't get an additional discount for not taking any phone
at all.
