Up for sale is a rare iPhone 6 Plus that is still running its near factory original OS (iOS 9.3.5). This phone is a 128GB model, the highest capacity ever offered with iPhone 6.

Once an iPhone is updated to a newer version of iOS, it cannot be downgraded later. 

Since almost all A9 devices (iPhone 6s, iPhone SE 1st gen) no longer activate on iOS 9, using an iPhone 6 is the next best way to experience iOS 9 as it was in 2015.

Additionally, in case anyone is unaware, iOS 9.3.5 can now be jailbroken on 64-bit devices via kok3shi (the device has not been jailbroken though).

The phone is in good cosmetic condition. The phone has no major flaws, but does show normal signs of wear. Expect a few small scratches, pits, or marks.

That being said, the phone is fully functional. All buttons and cameras work.

Also, this phone can NOT be used as a cell phone. It is SIM locked to a foreign carrier and cannot be unlocked.

Instead, this phone is intended to be used for playing classic mobile games and playing music.
