I also use Google calendar. I share a studio with 4 others and it's great for seeing when the studio is free.
Arrg. I have setup a second calendar in Google Calendar for the studio, but now, it refuses to sync to my iPhone calendar. It is not syncing with my Tempo app either.
I have my email setup as "Microsoft Exchange" on my iphone, instead of using "gmail". I know a lot of people recommend using Exchange instead. Somehow, i should be able to sync. I also went to the browser on my phone to sync multiple calendars, and even though the calendar is checked, it still will not sync. I have also restarted, and nothing..... Arrg
