We’ve got some rather intriguing information about what could be either HP’s webOS tablet, or an upcoming smartphone, that matches the quality of the iPhone 4 Retina Display. WebOS 2.0 is the hotly anticipated upgrade to Palm’s mobile OS, and it might’ve been outed through a game, of all things. Someone has been playing a game called Cloud Hopper on what looks to be webOS 2.0 — the game’s makers found this out through logs showing the hardware of the game’s players. More interestingly, the webOS 2.0 device was logged as having a screen resolution of 640 x 960, the same as the iPhone 4′s Retina Display. Is it HP’s webOS tablet? A new smartphone? We’ll hopefully find out soon.
