In case somebody missed it in the Mac Software forum, there are many Siri problems with non-5S devices and iOS 7. The worst is that you can disable find my iPhone, without having to unlock the iPhone.

BTW, is you are using iOS 7 on a non iPhone 5S device, then you should be aware that Siri is allowed to take commands when the lock screen is protected by a passcode. That means that somebody can grab your phone and do anything with Siri that would normally work with an unlocked phone! That includes turning on Airplane mode, so that Find my iPhone and remote wiping won't work, sending emails etc. and web look ups etc. The thief cannot access the rest of the phone, but Siri allows a lot of common tasks to be performed without unlocking the phone.

You can change this setting. If you go into the lock screen settings, you can turn off Siri access, just like you can turn off Control Panel access from the lock screen, which was recommended due to a similar problem (accessing alarm clock over the Control Panel, selecting turn off iPhone, then cancel to get into a locked iPhone.

I've just turned on passcode lock. I can access Siri but if I ask her to do anything she says I have to unlock the phone first.

I got my 5s this morning. Mmm new shiny.
