I have an iPhone 4 and was just wondering if they get the software update.
Does ioS7 work for the iPhone 4?
As long as you have an Iphone 4, 4S 5 5C, 5S then you can download it. Keep in mind though if you have below 10GB on your phone it won't work to download, because it takes up 3GB of space.
iOS 7 is available on September 18 for the iPhone 5, 4S and 4 as a free update.
It works but missing some features such as siri, airdrop etc.
