I'm evaluating ClieMail, In Box to go, and Iambic mail. They all have advantages based on their integration with their other programs, but the ClieMail integration is great with the standard Clie programs. Wonderful with camera, movie, sound recorder and Netfront.
In an attempt at getting these other programs to have similar integration, I found in the ClieMail preferences menu a mention of choosing the default mail program. Assuming you can set this to the other programs, you might get that integration. Anyone know what this "mailto tag" tag is, and how to change it to other programs?
