You could get a Firwire Cable or another "non suported" device, and plug it into the bottom then select yes when it asks you to enter airplane mode. You could put in a suggestion on the Apple Website for a "quick/quiet" mode on the iPhone.

No, unless u have a JB iphone. However, im not 100% sure, but isn't there some policy from apple against using software from accessing certain features like that on iphone? I have yet to see background wallpapers and icon changes so there must be some limiting factor.
anyone can correct me on this.?
Yes, especially for programs like Pathtracker (GPS plotter).. . . I just want to turn of all unused power hungry features with a tap, or maybe a key sequence.
Have u seen a JB application that could do this?
