Finally Motorola has introduced the Messaging and Security Feature Pack (i.e. AKU2 for Direct Push functionality) for the Motorola Q. Other improvements are:

-Dial-Up Networking (DUN). The Q can be used as a modem for another device, like a laptop or computer.
-Support for frames in the web browser
-SMS-to-Email functionality
-Bluetooth is being separated from this device’s Flight Mode, allowing users to listen to wireless headsets on airplanes.
