Something quite strange happens with Airplay on iPhone 4. If you "link" your phone to stream audio in the iPod app. Then quit but leave the Airplay button active. Your phones audio still streams over to the Apple TV or Airport Express etc.
For example, when you type the "clicks" are streamed over, and someone just called me and the phone rang via the Airport Express connected to my Hi-Fi. The same happens for New text messages, New Emails.
Feature or Bug? what do we think?
Hope it's a feature cause like it!
I always put my phone in the dock, either to sync, charge or just to know where it is and sometimes i can't ear an alert or incoming call when i'm outside or on the other side of the house
