There are two drawbacks that both have a workaround for wireless syncing. Your iPhone will wirelessly sync beautifully with your Google address book and calendar, however, it will no longer sync with your Apple address book or iCal. What a drag! Thankfully there is a workaround posted here for the address book issue (be sure to click on the “see all answers or post an answer…” link on this post). And here for the iCal issue (you have to set up iCal to subscribe to a calDAV account). After a bit of fiddling, everything is now up and running on my phone, computer and Google apps account! It is essentially the same as having a true Exchange account for my photography business, but without the annual cost.
As a photographer who spends a lot of time on the road, the iPhone has been a big blessing with its window to the web capabilities.During my pre-iPhone life I never had to worry about keeping things like email, calendars and address books in sync — because I worked off of one computer.Now that I have this terrific tiny top computer, keeping things in sync became a high priority to avoid the digital stress of duplication.
Looking into my options to accomplish this there was Mobile Me for $99 per year, purchasing a Exchange account for $120 per year, or the solution I finally settled on — Google Apps — for free.
NOTE:For the below steps to work, you will need to have administrative access to the MX records of your website.OR you can just follow the steps with a Gmail account – but then you don’t get the benefit of keeping your business email address.
