In London today Apple Inc (APPL:NYSE) announced the release of the new retinal and iris scanning application for the iPhone4.

"Users had always wondered why the iPhone 4 came with 2 camera's and now we can reveal why" said Arthur Ramsbottom at the Apple Research Centre in Cleckheaton, Yorkshire.

Ramsbottom said the new "app" will be called Eye-Eye and will utilise the on board camera to act as a biometric security device and will prevent unauthorised use of the phone.

When the app is active and the iPhone4 is picked up, a voice file will say "Eye-Eye" and the phone can then be place against the eye to scan the iris. If the scan is successful the iPhone will then say "aye-up" and the display will activate.

If the iris scan is unsuccessful then Ramsbottom explained that a new app called iSmell will be activated. Details on iSmell were not revealed today but obviously this will require the purchase of additional hardware which no doubt will be incorporated in the iPhone5 which will be coming out in August so all the numpties who bought an iPhone4 will have to trade up. Insiders say the iPhone 6 will be coming out in October to ensure that the iPhone 5 is obsolete before most people have taken them out of their boxes.
