LOL. I totally have to agree with you here.That said, I'm deeply amused at all the people who say a jailbroken phone is inherently unstable. I've jailbroken on four iOS versions so far, and had no major issues in spite of having a pretty heavily tweaked phone. Contrast that to darling hubby...who has been swearing at his fully updated iOS 8.xx iPhone 5 & iPad Air an awful lot lately.
Having a stable, jailbroken iPhone is all a matter of what you put on it. Well known devs within the JB community work hard to ensure their tweaks are as reliable as anything you'd get from the App Store (and more reliable than Apple, lately!) If you don't pirate apps and wait for others to try the newest tweaks first, you probably won't run into any major conflicts and your phone will continue to run smoothly...but with better functionality than Apple designed for it.
I am IT for my wife and many people I know. My wife's iPhone 5 has been jailbroken for over a year now because she wanted to use an Activator action for the flashlight function. Doing that required being jailbroken. She has a minimal set of tweaks and I generally only install things when I need to or have to. Bridge, Bolt, iFile, etc.
iOS 6.0.1, which is her OS has been rock stable and she's never reported a springboard crash to me. I'm not saying it's never happened, but it's such an infrequent thing it doesn't get mentioned to me. This iPhone of hers has been fine, good battery life and I have never had to take it to Apple for problems.
So, all the way around jailbreaking has been a benefit to her.
