I just purchased my iphone and am unhappy with the calendar feature. I would like to color code certain activities (personal, business, certain volunteer activities, etc. as I did in my Treo. I have looked at the app store and most seem to sync with Google calendar which does not seem to be color coded. I use Outlook. Does the basic iphone calendar have the capability to do what I am asking or do I need an app and which one? Also, I have aol and selected push email on settings, but I find the phone is searching for mail periodically rather than pushing it. Any input on that? thanks so much.
