Google Voice won’t be making an appearance on iPhones any time soon after Apple rejected it from the App Store. The reasoning behind the decision was that it duplicated existing functionality i.e. making calls, etc. It’s certainly a blow for iPhone users given that Android and Blackberry users can both use Google Voice. It also doesn’t bode well for the recently announced Spotify app, which again will duplicate existing features offered by Apple i.e. serving up music. Apple has developed a reputation for not allowing apps that it deems either unsuitable or in competition with its own services so Spotify and Google Voice may have a hard time overcoming Apple’s reservations.
