Another small stumble for BlackBerry. The company has pulled the latest update to its Twitter app for BlackBerry 10 following user complaints. Released on Dec. 17, Twitter version 10.2.2 for BB10 brought with it several enhancements, among them improved search, BlackBerry Messenger connectivity, and timeline photo previews. Unfortunately, it arrived with so many bugs that BlackBerry was forced to remove it from its BlackBerry World app store.
