We had once built a PhoneGap app for WP7 (alongside Android and iOS); the trouble was we didn't have a proper WP device, and the WP emulator has issues with VMware (it makes heavy use of the GPU IIRC). Native apps looked somewhat fine, but (whatever MS calls) WebViews wouldn't render. We ended up shipping it to the store without ever knowing if it even worked or not (faking screenshots via IE); and somehow it got accepted.<p>(Making this even sillier, Nokia had emailed us right before it got approved asking if we could make a proper Metro app for WP, not being aware of the PhoneGap app. They overnighted us a phone and I cranked out the app over four days, never having used the proper SDK before. Given the circumstances, it turned out pretty sharp. MS knows how to make good tools, I'll give them that.)
