In light of an earlier report claiming that a next-generation iPhone running iOS 7 has already been spotted in developer logs, it’s important to remember that not all iOS devices will receive the software update.
Apple routinely drops iOS support for older iPhone, iPad and iPod touch models, typically after a particular device has received two major iOS versions followed by a third version with limited features.
There are a number of devices that could be on the chopping block when iOS 7 rolls out next year, including the iPhone 3GS, iPhone 4, iPad 2 and fourth-generation iPod touch. The iPhone 3GS was fortunate enough to receive a feature-limited version of iOS 6, so it’s almost guaranteed not to see iOS 7. The iPhone 4 and fourth-generation iPod touch, on the other hand, are still sold by Apple, so they might live to run iOS 7 software.
The nearly two-year-old iPad 2 might also be in line for the iOS 7 update, since it has a more-than-capable Apple A5 processor that closely matches the A5X processor inside the third-generation iPad. But it’s hard to say which devices Apple will deem eligible for the software update, and one must wonder if it is based on legitimate reasons or done purposefully to get users with older devices to upgrade to the latest model.
