One of the big beefs folks have been bringing up against the iPhone is there is no ability to use Microsoft Exchange with it. This seems especially important to business users. This article on the PC World website talks about a new product from Synchronica. Synchronica is offering a secure gateway that uses Microsoft's Outlook Web Access (OWA) to retrieve email from the Exchange server.
What I'm wondering is will it merge with email system built into the iPhone, or is this just a web portal to your email which only works via the Safari web browser. I suppose that is better than nothing if you wanna have your iPhone and email too!
