I highly recommend the Elminster's solution which I performed myself. Having an Android mobile phone, it's great to have both Calendar and Contacts in full sync. Just don't forget to do the final step at the bottom for 'choosing which calendars to sync' so you can include all of your Google calendars. I have all my favorite NFL calendars from Google on my iPad. And, the best thing is the iPad calendar, even though it isn't that great, can still allow me to toggle on and off the preview of any of my different Google calendars.
The Exchange method works with mail as well. Thanks for the tip. I like having only one box now. Now my contacts, calendar and mail are sync'd across 5 devices.
