Back in 2010, Apple released 3 devices with the Apple A4 SoC which are the iPad 1, iPod Touch 4 and iPhone 4. Quite curiously, they only gave 512MB RAM to the iPhone 4 and left the iPod Touch 4/iPad 1 with only 256MB RAM, which went on to cause performance issues later on for these devices. The iPad 1 was killed off with iOS 6 and the iPod Touch 4 was killed off with iOS 7 but the iPhone 4 stayed until iOS 7.1.2 even though it didn’t run it too well.
A couple of years ago, dual-booting versions of iOS on older 32-bit Apple devices became something quite easily achievable and of course, some people decided to try unsupported versions of iOS on their devices just for fun! Recently, a Twitter user called Raffaele tweeted his iPod Touch 4 running iOS 7 and that got me interested. Obviously, the reason why the iPod Touch 4 could run iOS 7 for the iPhone 4 is because their hardware is quite similar but it’s not quite as similar as some may think…
