Apple/carriers don't do OTA firmware updates on the iPhone. It's your choice to install the update or not.

  While it's better that the device isn't updated automatically, it's the same effect; I assume Apple bills these updates as essential for security and functionality features, so one may assume it's necessary and install over their stuff, perhaps unknowingly (if a friend administered the jailbreak, or if they didn't pay much attention and just assume it works with updates). It's really just not worth the hassle, honestly. I will never own an iPhone primarily for these reasons.
