by using sbsettings?
I just downloaded respiring from cydia, clicked the app icon and everything was back to normal.
i was just curious if any one jailbreaked, there iPad and noticed the wifi logo gone missing?
i've had it gone missing twice untill i restored it twice.
So far, so good. No dropouts today since I restored.I'm having the problems as you have described. Did you notice if it was the same before jailbreak or only after.
I've restored mine to test.
