Once the toolkit is available. I used to jailbreak a lot in the era of iOS 2, 3 and 4. I tried to jailbreak again on my iPhone 5 - mainly because I was fed up with 2 huge gray bars in the lockscreen which blocked my view of the wallpaper - but with the release of iOS 7, the problem is solved. As Apple is adding more and more stuff into the OS, I don't find the need to jailbreak anymore. (well, maybe I still want to have the tweak of showing avatars/small pictures in contact list/texts, but I can live without it).
