Leaked high resolution images of a taller iPhone casing reportedly match up to a prototype being tested internally at Apple, according to 9to5Mac.
Sources in position to know say that the structure of the shells do match up with what is being tested internally. Namely, the redesigned bottom portion of the iPhone with the moved headphone jack and smaller dock connector are present on at least one of the longer iPhones that Apple is testing internally.
Earlier today a schematic for a taller iPhone was also leaked online. Unfortunately, as compelling these leaks might be, last year showed us that there is really no way to determine with certainty what design Apple plans to release later this year.
