There's word that if an app is unapproved and removed from Marketplace for Mobile, Microsoft's version of Apple's App Store, then it will also be removed from all users' devices. No information on whether that includes refunds for paid apps.
You name it, we've got it: Sexy search tools! Google Voice! Upstart app stores! Maps, with stuff on them! Radio! Emulators, from the future! Fresh new browsers! It's all in a
day's month's work for Windows Mobile.
