I'm not going to get instabilities and hard to upgrade devices just for SBSettings or alike.
Unfortunately too many people only jailbreak so that they can install software for free.
That said it completely sucks that Apple does not allow me to be in control of what I want to install, including apps downloaded from a web site.
Also, a lot of people install SBSettings just because how freaking lame is the iOS algorithm to understand how bright the screen should be a given light level. Lame.
Now that iPhones are more or less officially on Straight Talk (vie Walmart), there might be a better solution.
Swipebright is my poison.
