Loving my Droid X. Previous phones: Eris, Droid1, BB Storm, BB Curve 8330, LG Dare, LG Chocolate 1 & 2, and lots of other LG dumbphones...
If you are still looking for a Calendar app I have MOD'd the original calendar and pushed it to the Market.
Calendar Plus I have both a free version and a paid version. The Free version is a basic model almost identical to the original but with a few wanted addons.. The paid version, I have added new features such as:
Fading past events
MutliDay View (1-14)
Explicit Start View settings (So you can specify "DayView/WeekView/etc..." to be the start screen)
Changeable Default event length (instead of being stuck with 1hr as the default)
I am always trying to add new features that users feel have been left out of the original app.
