The image on the left shows what an edge-to-edge screen would look like. As far as whether or not it’s real, we don’t know.
Here’s more evidence of the edge-to-edge screen we’ve heard so much about for the iPhone 5. This may not confirm it, but website 9to5Mac spotted these in screenshots from SpeechTrans Ultimate, which is powered by Nuance. If the images are real, they show an iPhone with a 4-inch screen, which may be a render of the iPhone 5.
According to the report, Nuance is working closely with Apple to improve their speech recognition. We cannot confirm the validity of these photos or reports, so we will just leave you with the images to decide for yourself.
