The DOF scale I was looking for...

I was searching for one of these awhile back and finally found it. It is a Depth of Field scale that shows what will be in focus at a given aperture /distance/focal length....that runs from my smartphone. I haven't tested it's accuracy, but he claims to have used data from DOFMaster (which is widely used) to get the results.

I am not sure whether an application unlock would be required for a smartphone running Windows Mobile 6, but I can vouch that it is compatible on a Samsung Blackjack2 running Windows Mobile 6.1 that is NOT application "unlocked".

Here is a link to the site...
