Again, with the exception of the newly designed iPhone 8, most of the benefits will be in the new iOS11 software. That means that current iPhone 7, and iPhone 6 series users will also get some cool new functionality. We've also heard that the memory configuration of the 7s series will be 32GB, 128GB and 256GB. Speculation is the iPhone 8 will offer 128GB or 256GB with 512GB coming early next year.
Warning... If you have an iPhone 5C or earlier, sell it or trade it in ASAP. Once Apple's new iOS11 rolls out, the earlier iPhones will no longer be supported, No security patches will make it easier for the bad hombres.
