Getting an iphone can be fun. Finding a way to make it work with mail and calendars can be tricky.
I recommend getting a Gmail account and then following two sets of instructions:
First, goto gmail.com and set up an account. Then do these two things:
– Sync your email, contacts and calendars by following this guide:
http://www.sync-iphone.com/transfer-iphone-to-itunes/sync-iphone-with-gmail.html
– Enable multiple calendar syncing by visiting this site ON YOUR IPHONE:
http://www.google.com/mobile/sync/
And do do it that way around so you get the basic thing working before mucking around with calendars.
You’ll also notice in IOS 5 that you can change calendar colours so they match your Google calendar ones. Hooray!
