if you are asking in context of the iPhone, then I don't think you are allowed to do that with the official SDK.

You should look at the source code of the unlock tools by the team because they send AT commands to read data from the iphone modem.

I don't know what kind of functionality you need, but this website took me quiet far in sending text messages with the AT command set.

Furthermore you can use the windows hyperterminal (Accessories>Communication) to connect to the specific USB port (mapped on a COM port). With this connection you can send AT commands yourself to the cell phone and see what it returns.

Hope this helps...
