I've read a lot about accessing contact details or posting to social networks without needing the passcode of the phone, but did not manage to find any information about bypassing the lockscreen entirely. I was asking siri for the definition for a word and selected the option from the list given. after which I pressed the home button to close safari and low and behold, i was back at my home screen, WITHOUT ever entering my passcode. Has that been around for awhile? would be a big bummer to not be able to set a timer without having to enter my passcode.
