Jott for Blackberry

With Jott, you sign up for the (FREE) service by going to www.jott.com , and set up an account. You can then upload your selected contacts from Outlook to their server. Here's a description of the service from their Website:

Jott is a simple, but very powerful tool that will let you reply to emails on your BlackBerry just using your voice - either speaking directly into your BlackBerry, or while wearing a Bluetooth headset. It is seamlessly integrated into the email application you already use, and is a huge leap forward for BlackBerry lovers in three ways: first, it is 3-5 times faster than 'thumbing' text; two, you won't be known for sending just terse replies because you don't want to thumb type out a normal email message; and three, you will be safer because you won't have to take your eyes off the road.

So far I've found that the replies that I send to my Emails are not perfect, but you can spell out the word and fix that. And they aren't reliably quick (depends on how busy they are at the moment), so I'm not using it for time-sensitive replies.

But it saves lots of thumb-strokes and I love it!
