According to a tweet by the official Google Voice Twitter account, Google has pulled the Voice for iOS app from the iTunes App Store. Google decided to pull the app due to its crashing on startup, which was introduced with iOS 5 (Couldn’t sort it out in 3 months of iOS5Beta?). Google says hang tight for the time being, because they’ll be updating/rereleasing the app again. Tweet:
Removed the iPhone app from the App store. We’ll have a new version for you ASAP with a fix for the sign in bug.
