Thanks. I've used SBsettings in the past but am not using it now. What I'd like is a toggle switch directly on the Springboard screen itself...so there is just one thumb press...not a swipe that may or may not take, then a button push, then pressing a small "x" to close the app.
SBsettings can be dropped down by holding your finger on the status bar instead of swiping your finger across it and you can exit SBsettings by pressing the Home button instead of pressing the small X. Those were my two gripes about it as well.
I feel you on the need for the icon though. I waited forever for an airplane mode version which I now use iphone tools for.
