A recent report claimed that Apple is already testing iOS 9, the next-gen mobile operating system that’s supposed to be unveiled this summer and launch later in fall. Now, mobile app marketing platform Fiksu has confirmed that Apple is indeed testing the iOS on a variety of mobile devices including the brand new iPhone 6 and iPhone 6 Plus.
The company says that it has spotted 145 distinct Identifier for Advertisers (IDFAs) so far this year belonging to iOS 9 devices, TechCrunch reports. It’s likely that each IDFA is tied to a distinct iOS device, as users generally don’t reset them — resetting the identifier for privacy reasons can be done, but it’s not a common activity that testers might be actually interested in.
According to the data, 63% of the spotted iOS 9 devices are iPhone 6 and/or iPhone 6 Plus models, 12% are iPad Air 2s, 12% are iPhone 5s units and 13% are “everything else.”
These iOS 9 devices have been spotted all over the world, including the U.S., China, Czech Republic and other countries, though 92% of sightings revealed U.S.-based devices.
In addition to iOS 9, Apple is also working on at least two iOS 8.x releases, including iOS 8.2 and iOS 8.3, with the former expected to soon enable Apple Watch functionality.
