@[email protected] @[email protected] My wife had a Helix Ocean phone right before the iPhone hit the market. Amazing phone with two sliders — one in landscape for a QWERTY keyboard, and one in portrait for a numeric pad. If it were just modernized, with a hi-res touchscreen, it would be amazing today. (Although admittedly the two sliders made it very thick to hold and use.)
I think the phone predated this patent, although I imagine the patent didn’t apply anyway since it was a phone and not a gaming handheld.
