BootNeuter. Not an official app, but ugly as hell and I hate seeing it. Only for jailbroken iPhone 2Gs. I don't actually know what it does, but I just haven't deleted it because I'm too scared that it will screw up my JB.
you can use SBsettings to make the icon disappear, it wont delete it, itll just make the icon go away, and then use the Spotlight thing to get to it if you ever need it.
worst icons This thinng just popped up out of the blue... I don't know how the computer got it! I really need help getting rid of it but I don't know how!
