Apple has maintained its cycle of releasing new iPhone, iPad and iPod touch models once per calendar year, meaning that there is increasing fragmentation of iOS devices and versions in the hands of users. As the hardware specifications of older devices begin to lag behind, Apple has steadily raised the minimum software version for App Store downloads.
At this point, most apps require iOS 4.3 or later in order to be installed. That leaves millions of users with older iOS devices out of luck when attempting to install popular apps such as Facebook, Candy Crush Saga, Temple Run and Minecraft: Pocket Edition. But, fortunately, there is now a solution.
Apple has introduced a new iOS feature that allows for users with older devices to install the “last compatible version” of apps available. The discovery was made on Reddit and picked up by Engadget, which confirmed that it was able to install an older version of Instagram on an iPhone 3GS running iOS 4.3.3.
