Cut price iPhone in exchange for watching ads?

Could a cut-price iPhone be about to appear? There is a new patent with Steve Jobs name on from Apple that talks of an invention for viewing ads on mobile devices, (seen on Slashdot) where the device locks until the ad has been viewed, it includes a 'process' where by the viewer must verify their presence before continuing normal use, i.e. you can't walk away and make a cup of tea. See full patent HERE*.

I wonder if this is an Apple version of the Blyk concept of free mobiles for teenagers in exchange for taking part in research and viewing ads. Apple have previous with education aimed devices.

If this was linked say to the new Apple netbrowser/tablet/mega iphone  that's widely rumoured to appear in 2010 all the more interesting. The app store trend and the beginnings of an Augmented Reality advertising market does mean a rethink for the models of revenue generation across mobile devices. Has Apple jumped the gun by building in such capabilities to its new 2010 products?
