My last phone was a Samsung SPHi500, a smart phone that used the Palm operating system. I was synchronizing with ACT! I had trouble with the synchronizing, so I started using CompanionLink Express. After checking with the tech support people, I found I needed Outlook. I bought Outlook 2007 and I can now synch all of my ACT! contacts and calendars with the iPhone. My new question: When will there be a Documents to Go version that will help me synch Microsoft Office files with the iPHone?
