I have my phone syncing with two gmail accounts, both of which have a calendar. Each of these calendars is shared with the other calendar, meaning that on my desktop computer, my A calendar can see B's events; and my B calendar displays A's events.

Everything shows up correctly on the phone, HOWEVER, on the phone I can edit events from one calendar BUT not the other.

Note: The account I CAN edit from the phone is the one that matches the gmail account used to setup my Palm Profile.
