I'm unable to get either the 2.1 SDK or the 3.0 beta SDK to work with any GSM 1900 Nokia phones using the SMS APIs. We need to be able to send and recieve text and binary SMS and I want the connection method to be a cable.

It seems to work fine on a number of 900/1800 phones for developers on my team who are in Europe.

Anyone reliably using the SMS APIs in the US?
