I recently jailbroke my iphone 4 ios5 with the redsnow tethered JB, and I came across a weird problem the other day that I cant find an answer too. I usually put my phone into airplane mode if im somewhere that im not getting a good 3G signal in order to save battery, but the other day I tried to go into airplane mode and the airplane icon appears on the top bar and the phone appears to be in airplane mode, but then I noticed that every so often, an email or SMS was sneaking through when the phone caught a bit of signal, and my battery was also still draining like crazy like it would if it was just on regular and searching for signal. So it appears my phone isnt really in airplane mode even though it says it is, and it did this both by going into airplane mode through the SBSettings toggle and the regular airplane mode switch under settings. Anyone know a way to fix this and make the phone actually go into airplane mode? Reason im posting this in the jailbreak forum is because it didnt do this when I was running normal ios5, or when i was JB'd on ios4, so im assuming it has something to do with the redsnow tethered JB.
