I used Splash ID on my Palm. When I made the switch to the Blackberry, adding this was a no-brainer. Blackberry cool takes a look and reviews:

Overall, I consider this a great tool for really anyone. You never know when your mind’ll go blank and you need to remember your cousin’s clothing size (yes, adding a clothing size is an option), and given the amount of information that’s needed to function in today’s society, Splash ID is a blessing. I’ll take my red pen and give this great application a solid “B” rating.
