I'm trying to transition some clients apps to Windows Phone 8. These particular clients want their apps to look exactly like they do on iOS and Android (I tried to convince them they shouldn't look the same on those platforms either, but I digress). Anyway I was under the belief that it would be very difficult to actually create a WP8 app that looked exactly like an iOS app, and that if a developer submitted an app like that it would be unlikely to pass Microsoft's review process.
I can't find any confirmation one way or the other on whether or not an iOS-like design would be acceptable the Windows Marketplace.
