I think the time has started when we would be different leaked images of next iPod touch and iPhone and some of them also turn up as just fake ones.Few days ago we say some leaked images of next iPod touch and today another picture of iPod touch prototype is leaked.
Again this leaked prototype is showing that it has a capacitative home button which to be honest looks quite good on it.But still their is a big possibility that this image is real as I think this is quite early to say anything about a design of the device which would launch about 5 months from now.
