Just had my annual IGS a couple months ago. According to one of the slides the instructor had up, the Fore Flight app on your (insert your favorite hand held device here) is now authorized for use in the aircraft. You can load all the pubs you'll need on the device before you fly, and you can have the GPS on the device working while in flight. You still need to have the paper pubs in the jet to be legal. I'll try to track the guy down so I can get the actual regs on this.
