Iphone 7 rumors

The rumors for the iPhone 7 is that it will have cordless charging, 3D screen and shatterproof saphire glass. It's supposed to be released in the Spring. Apple keeps improving the phones so people can keep upgrading to make money. If they make it with everything they can people wouldn't buy new phones. I don't know if the 7 will have all the features they say because the rumors are not always true.
