OneKey Maintainer Sets iPhone 17 and iOS 27 as Cold Wallet Minimum

This is a notable escalation in cold-storage hygiene rhetoric: a hardware-wallet maintainer treating a phone's OS version and model generation as a security boundary, not a convenience. It effectively narrows the viable device pool for anyone considering an air-gapped iPhone setup, and raises the recurring cost of staying current. The cited CBP device-search figures give the argument a state-access dimension beyond ordinary malware risk. Whether other wallet makers adopt similarly strict device floors — and how users weigh annual hardware churn against that threat model — is the open question.
