I drank the Kool-Aid

Over the weekend my father was upgrading his 2G iPhone to the 3G model. I had himmed and hawwed about getting the iPhone or waiting for the Blackberry Bold. Screw it, I got the new 3G iPhone, the 8GB model. Now I’m basically loading up on the needed accessories, a case, extra sync/power cable, apps from the app store. The one thing that I’ve come to rely on is the calendar. Before with my Windows Treo 750, I was syncing my calendar on the device to Google Calendar. Now I know that there are a bunch of Third-Party apps that filter my entries via another service, that scares the shit out of me. I’d rather just have a direct link between my calendar on the iPhone and gCalendar. Even if it’s only one-way, I’d take that.

Any help?
