Reaffirming the widely reported and credible rumor claiming the next iPhone will sport a taller four-inch display, a part leak has surfaced today indicating that the next iPod touch will also adopt a taller, 3.95-inch display.

As you can see, a claimed front panel from the next-generation iPod touch is taller compared to the current-generation iPod touch which has the same 3.5-inch Retina display like the iPhone 4/4S. This particular part measures in at 4.1 inches diagonally and has a hole for the physical home button right where you’d expect it…

It was leaked by a parts supplier and MacRumors got hold of it.

The publication also pointed to the home button flex cable and front and rear camera parts, seen below. These are said to belong to the next iPhone, though they warn a supplier hasn’t yet confirmed their authenticity.

Unfortunately, the image is too small and we couldn’t decipher what the label says in order to eventually determine the camera brand.

It’s been assumed the next iPhone will increase the back camera resolution to at least ten megapixels, but thus far no evidence emerged to substantiate this specualtion

Back in January, Sony unveiled a new tiny 13-megapixel CMOS image sensor with HDR Video that could be a perfect fit for an ultra-thin iPhone 5.

Here’s a demo of the HDR Movie function it provides

According to a press release, Sony’s new CMOS uses their unique “RGBW Coding” function which allows images to be captured with low noise and high picture quality even in low-light conditions. The new  HDR (High Dynamic Range) Movie function allows brilliant color to be captured even in bright settings.

9to5Mac today chimed in with some new info pertaining to the iPhone 5, or whatever it ends up being called.

The publication has it on good authority that Apple is already testing prototypes of the next iPhone which sport a 3.95-inch display with a 1,136-by-640 pixel resolution.

Despite concerns that changing the form factor will break third-party apps, developers reportedly aren’t too concerned, believing Apple will either use the extra pixels for new interface controls or provide tools to make the transition as painless as possible.

In theory, most apps would automatically adapt themselves to a taller representation by simply scaling up their content canvas a bit. Only graphics-intensive 3D games would need to be re-written with a taller display in mind.

We should find out more about the next iPhone at Apple’s annual developers conference, which kicks off on June 11 at San Francisco’s Moscone West.

According to our poll (take it now), nearly one in two readers wouldn’t object to a four-inch iPhone whatsoever, while one in five preferring a 4.3-inch display like on the Samsung Galaxy S II.

Excited?
