Send UDP data over GSM / GPRS

I have an Arduino Uno and the latest Arduino GSM Shield. I am able to use the example sketch and connect to a web page (http) using GPRS. My problem is the project requires data be sent using UDP. I can't find any good examples for sending UDP Data with the GSM Shield.

The Arduino tutorials has a great example for sending UDP data with the Ethernet Shield. The example uses the EthernetUDP class, but there doesn't seem to be a matching GsmUDP class or GprsUDP class. http://arduino.cc/en/Tutorial/UDPSendReceiveString

I will probably need to use AT Commands for this, but I can't find any good examples for sending UDP data with AT Commands.

Does anyone have some example code for this? Or know where I can get some?

(I also need to receive UDP data sent to the Arduino, but I'm focusing on sending UDP data first.) Thanks in advance!
