I see the new offering from Google for contact and calendar syncing via "Exchange Support" but have a few questions: Say, I'm already using Mobile Me - can I use Google Sync? If I use Google Sync, will it just sync my iPhone and online Google Calendar? If so, what about the calendars in iCal? Will they only be read only? I'm interested in trying this out, but I also want to be able to add contacts in Apple Contacts and calendar items in iCal. Did anyone try this yet?
