With a video camera built into your Windows Mobile smartphone you can record yourself, or anyone else, and send the recording as an MMS (multimedia) message.
Select your device's camera function
From the camera's options, select video messaging (this icon will look like a movie camera with either an envelope or MMS on it).
Shoot the video you want.
When your video clip shows up in the review panel, either select "Send" from the menu or click the envelope icon (if you have one).
Select the account from which you wish to send the video clip
Enter the recipient's address and a message (if you wish)
Hit the send button.
Quality of the recording and playback will obviously depend on your device, and the recipient's, as well as the resolution settings you choose.
