Todo+Cal+Sync for iPhone: alert sound and message ?

[merat]

Using the original iPhone Calendar, at alert time, we hear a sound and see a message.

Using the Todo+Cal+Sync for iPhone, the alert is synchronized with the server but it has no effect on the iPhone: no sound, no message, no vibration.

What am I missing ?

It is explained here.

At this time, there are two limitations set by Apple's iPhone SDK: Apple does not allow to access the internal iPhone calendar, nor sync with iCal, so the calendar in Todo+Cal works independently from the built-in iPhone calendar. Second, Apple does not allow reminder alerts. We hope Apple will lift these restrictions, so we can integrate the functionality.

Hopefully a solution is found soon. Otherwise a GREAT application.
