An image of what might be an iPhone 5 part has shown up on a parts reseller website in China. Some theororize that it’s an iPhone 5 digitizer panel. If that’s the case, then we are looking at a much thinner bezel for the upcoming iPhone. The part would also suggest a much larger display, in the area of 4 inches.
There have been previous reports of Apple looking to create an “edge-to-edge” display. MacRumors reports that the source, iDealsChina, has had a mixed record when it comes to predicting new devices based upon parts offered at their online store.

Hope this is true I want a bigger screen for the next iPhone with the same dimensions.
I want more. I dunno what. But if they gonna keep coming out with a iPhone every year. I want more
wouldn’t a larger screen = sacrificing battery life?

If the phone is bigger, that means the battery would also be bigger.
