OneKey Founder: iPhone Can Be Turned Into a Cold Wallet, but iPhone 17 or Newer Is Recommended

PANews reported on October 14 that OneKey founder Yishi published a post discussing how to turn an iPhone into a cold wallet, stating that the minimum recommendation is to use an iPhone 17 or newer running iOS 27 or later, and to replace the device every 1 to 2 years. Yishi emphasized that this is only a personal security recommendation, not an official Apple certification or security guarantee, and that even if older devices are disconnected from the internet, the risk of someone gaining physical access to the phone cannot be eliminated.
