Jott: Hands free note taking and messaging
I often use the voice recorder of my Pocket PC to take notes when I drive or when I walk but I have to transcribe them later. Jott solves the problem, and it works with any phone: just call and leave a message to yourself or anyone else. Jott analyses the message and sends a mail with the transcribed text and an audio attachment.
A great service but currently only available in USA and Canada.
