Hi, I did a search, but didn't find an exact explanation or confirmation of what I am trying to do before I decide to buy an iPhone. My Needs: Work uses MS Exchange for email, calendar, and contacts. Personal use Google calendar, email, and contacts. 1) Does iPhone 3.0 allow me to use both Google Calendar and MS Exchange calendars in a combined single iPhone Calendar Applicationview? 2) If it does, will I be able to make changes to each of my 2 calendars? 3) Will the Iphone keep my 2 calendar servers separate, and not try to combine the calendars and upload my personal to my work or my work to my personal calendar at the server level? Thanks so much!
