To my opinion the Missingsync application is NOT tested thoroughly. It corrupts my mac as well as the telephone!!! The application was no help and no use, I provides me even more problems.

Missingsync for symbian phone sony ericsson P1i damages entouragedatabase on my mac osx! Couldn't start entourage anymore. The database of entourage is corrupt. Need a complete new install, not talking about all the missing data. Missingsync is a crappy application. It is not only errors that I found in the logfile, but destroying your entourage database...

And the tasks-button on the phone was also damaged, no tasks anymore for the phone.

This is a serious flaw. Now I have two unusable machines and an unstable application. And need expensive time to repair it.
