Just a quick shout out to Neil Enns (PM on the Visual Studio Devices team) who resolved my concern that I couldn't disconnect my new Audiovox smartphone from the GPRS network.  Apparently, once the connection is established to the data network the Smartphone 2003 OS tries to keep the connection to make future requests speedier.  I was concerned that something was wrong or that there would be an issues with the battery life, but from his comments they are drained mostly when you initiate packet transfers.  Good to know.  Keep answering those newsgroup posts Neil! No doubt I'm not the only customer who has been helped by your replies.
