Kudos to programme Barak Harel for coming up with a viable way for mere mortals to 'sign' low level utilities for S60 and Symbian OS. Having started trying to sign RotateMe a week or two ago and given up in frustration, this sort of Windows utility is extremely welcome. You'll still need a Symbian 'key' and 'cer' file, but other than that it's supposed to be totally automatic. Anyone tried it yet?
