Via Digg and Unwired View:

Apple filed for clamshell iPhone patent. The idea is to separate phone display and touch sensor array. Put the array on transparent panel and connect it to the display via hinge. When closed - it’s standard iPhone. Open it and the cover becomes a trackpad to control the phone. The same tech fits iTablet and brings Vista Sideshow like display to Mac…

It would be awesome to see an iPhone clamsell like phone with a clear display on the second screen. Only Apple knows what technology it has, they are always 15 years ahead of everyone else in technology. Yes, thats the Apple geek in me coming out
