While Apple has been as coy as ever on what it has in the pipeline, here’s what we can likely expect from the next iPhone launch. First, the unveiling of the next Apple smartphone should occur in early fall, perhaps as soon as mid-September. Second, pundits bet the next model will veer away from the traditional numerical naming system, instead being called iPhone Air. According to leaked snaps circulated on Reddit, the iPhone could boast a larger screen than what the current four-inch models have. Lastly, backloaded revenue from Apple supplier GT Advanced Technologies indicates this model will use sapphire crystal for its display screen material.
