Rumor has it that the next generation of the iPhone is coming to us in September. What it will look like and what it will do differently, we will have to wait to see. Sources are now confessing to seeing prototypes of the device. A larger screen, which we all want, is definitely one of the new features. It's also been said that the new phone's screen will be made out of sapphire for increased durability. With that being, the 5c's minimal success is said to be continued through a cheaper-made 5s model.
It has also been reported that two different phones will be available, one with a 4.7 inch screen and another with a 5.5 inch. The reason for this differentiation is not yet known but could have something to do with the fact that the iPhone's competitors all have larger screens. As far as the smaller one goes, maybe Apple is trying to stick to their classic iPhone look. After all, the past released models have all been just slightly different, with the same design still the same.
Another rumor is that the home screen button will disappear. If Apple is really trying to keep their "design", the absence of this universal feature of the phone will go against that. What exactly they plan to do is still unknown. What we do know is that the IOS 8 will also be introduced this year. As in the past, with the release of a new model comes new updated software for all devices.
