Just to make sure that the iPhone 4s is still relevant three years after its launch, Apple has been seeding developers with the iOS 8.1.1 beta. Release notes for the update indicate that it includes "increased stability and performance improvements for iPad 2 and iPhone 4s." By making the greybeards run as though they consumed a glass of prune juice, the update could allow iPhone 4s and iPad 2 owners to escape paying for an upgrade, at least for now. Both the iPhone 4s and iPad 2 slowed down after the iOS 7 update, so hopefully iOS 8.1.1 is the fountain of youth for both devices. The update also includes bug fixes.
The adoption rate for iOS 8 is a little more than 50%, which is the slowest rate ever achieved by an iOS update. One feature that many are hoping to find on the new iOS build, is the multitasking split-screen function available on rivals like the Samsung Galaxy Note 4. Apple hopes to have the split-screen, which allows two applications to be on the display and active at the same time, available for iPads and the 5.5-inch Apple iPhone 6 Plus.
