iPhone 4 and iPad 2 are some of the Apple devices that may no longer receive the iOS 8 update when it rolls out early next month.

Apple is planning to announce the next generation of its mobile and desktop operating system – iOS 8 and Mac OS X 10.10, on its annual WorldWide Developers' Conference on June 2 to 6, 2014. During the release of new iOS, iPhone users were concerned whether their devices will receive the update or they will be forced to upgrade their unit.

Based on previous Apple releases, every time the company upgrades its mobile software, Apple no longer supports one or two previous models. This year, Apple still has not confirmed which of its devices will make the cut.

The rumored iPhone 6, iPad Air 2 and iPad Mini 3 will come pre-installed with iOS 8. According to MacWorld, iOS 8 will support iPhone 4S as well as the newer models of iPhones. As for the iPad line, the iPad 3 onwards will be supported by iOS 8 leaving iPad 2 behind. The fifth generation of Apple's iPod will definitely be supported by the next iOS 8.

Aside from iOS 8 and Mac OS X 10.10, BGR cited Financial Times claiming that Apple will introduce another "a new software platform" at the WWDC 2014 event that will allow Apple users to control the lights, appliances and security systems in their homes, making it a smart home. The report also added that the new platform from Apple will give it an advantage over Google and Samsung.

The new smart home software platform will pack common automation features that are found in similar platforms or software. However, it is unspecified if Apple's iBeacon technology will be used in this new platform. The Cupertino-based company is reportedly working with various manufacturers of appliances, which will offer devices and accessories for the company's new smart home platform.
