Remember those old push-to-talk phones? You know, the ones that basically worked like a walkie-talkie, letting people chat without connecting to a cellular network or dialing a phone number? As it turns out, Apple might’ve tried to stick a walkie-talkie-like feature of its own on future iPhones. The feature has since been put on hold.

A report by The Information states Apple was working with Intel on the technology. It was codenamed Project OGRS (Off Grid Radio Service) at Apple and Project Shrek at Intel. Who says giant tech corporations don’t have a sense of humor?
