Something apparently has Siri's tongue.
For a third day, Siri is suffering intermittent failures that is preventing Apple customers from using the much-touted voice-activated virtual assistant for the new iPhone 4S.
When it's working, Siri lets users schedule appointments, dictate texts and do Web searches with voice commands. While Siri had moments on Thursday and Friday when it was restored, it quicky became unavailable again.
What has been most troubling for some users is that Siri primarily depends on a network connection when a number of tasks, for instance, linking to a user's callendar or playing music stored on an iPhone, wouldn't seem to require access to the Internet.
