Although Apple’s new iPhone 4S is still proving a popular smartphone to own this Christmas, let’s not forget that rumors surrounding a possible 2012 iPhone 5 are still rife on the old rumor mill! Just the other day we brought you two articles, which spoke about how Hitachi and Sony were both supplying and shipping LCD displays for the new iPhone 5, as well as a new design “iCam” concept which would revolutionize the way in which the iPhone takes photos.

Today as we continue to give you what are just purely rumors at the moment, a new report from Germany has spoken about how the Cali company Apple, are in fact testing out new CPU’s, GPU’s, impressive higher resolutions and aspect ratios.

Courtesy of cultofmac.com, John Brownlee has been keen to report on Apple supposedly testing out different configurations for upcoming iPhones, which could result in various dual-core and quad-core mediums. Resolutions of the smartphone that are rumored to be tested, include not just the Retina Display with a 960 x 640 resolution, but a 720p device with 1280 x 720 resolution, matching that of the LG Nitro HD that we spoke about the other day, along with a massive 1440 x 800 phone or possibly 1440 x 900.

Aspect ratios of a new iPhone could therefore be upped from a 3:2 that is currently being used, to a massive 16:9 being seen with the 720p display. For now our advice is to take this news with a pinch of salt, but it cannot be totally disregarded, let’s face it Apple do like to keep us on our toes.

What are your thoughts on a new 2012 iPhone releasing with a higher density display and bigger aspect ratio?
