Security firm Sophos warns iPhone 4S owners to check settings to close security hole in Siri. Even a passcode-locked phone is vulnerable to the flaw. Sophos consultant Graham Cluley advises using a more complex passcode.

We’re rather more positive about Siri – we reckon it beats Android’s Voice Actions easily, though it’s still official beta.”]
