Want more proof or confirmation that HP really does not plan to continue webOS for tablets and smartphones? It seems that in an internal AT&T memo, the HP Pre 3 smartphone will be seeing its launch cancelled, along with any packaging or promo material to be stopped working on immediately. It’s really not surprising that AT&T has made this move, but interestingly it’s good to know that there was at least one carrier who had plans to launch the device on their network, a device which was announced earlier this year in February.
