GPRS is definitely the way to go, in the states T-Mobile and Cingular are
two providers I've used although I have a personal bias toward t-mobile.
If you're using Datasets, then you don't need sql server CE on the device,
you'll get the data back as a DataSet (XML) and can use it directly. As far
as Web Services and CF development - Casey Chesnut at www.brains-n-brawn.com
probably has the coolest samples of doing some pretty complex stuff (the
whole site is cool - not just the PDA stuff). Similarly, you'll definitely
want to check out the SDF at www.opennetcf.org which is the best CF
reference on the web. The web servcies will be located on a web server
somewhere - that's up to you but if you want to plug into a few samples I
think Casey has some exposed and if not - the GOogle API is a great one to
use.
