If you’re currently rockin’ a smartphone running Windows Mobile 6 or higher, it’s time to get on the MyPhone wagon. Microsoft’s new OTA backup system is now in open beta and is ripe for the picking. You get 200MB of free storage, which isn’t a whole lot, but it should make do for emails, contacts and calendar events for now. It’s a nice little taste of what a Microsoft Exchange Server will do for you, but nowhere near the same scale of course. Speaking of Exchange, MyPhone will not work if your phone is currently synced with an Exchange server — but then again if you’re using Exchange, you wouldn’t really need it. The price is right and feedback so far is positive so, Windows Mobile users, get going.
