In response to circulating rumors regarding Windows Phone 8's lack of application backwards compatibility, Microsoft's Brandon Watson -- Director of Developer Experience -- confirmed today that the upcoming OS revision will run older Windows Phone 7 applications. Yep, that means Sally's Salon will port over just fine.
But from a technical perspective, how existing apps will work unmodified is fuzzy. For example, if the new resolution rumors pan out, should we expect some sort of zooming functionality akin to Apple's iPad (running iPhone applications)? And what about those awesome premium apps (e.g. Youtube, Tango, Navigon) with native hooks into the underlying OS? We presume everyone using native code is on Windows Phone for the long haul, but it's worth asking.
Anyway, stay tuned. We expect both Windows Phone "Tango" and "Apollo" to be detailed at Mobile World Congress next month. Rest assured we'll have feet -- at least Daniel Rubino's -- on the ground providing updates.
