update:-
using ios-sdk 6.1 compile extension , testing on iphone 4 (ios version 4.3.1). testing on iphone 5 (ios version 6.0.0), , flash turning on, not turning off. guess might help.

that code copied may have error in it. try following:

-(void)turnonflash {     avcapturedevice *device = [avcapturedevice defaultdevicewithmediatype:avmediatypevideo];         if ([device hastorch]) {             [device lockforconfiguration:nil];             [device settorchmode:avcapturetorchmodeoff];             [device unlockforconfiguration];         } }
