I also have shsh for ios 5.1.1 and 5.0.1. So far, 5.0.1 is the smoothest because 5.1.1 laggs when closing camera app. Also on iOS 6, it lags only if I switch the web pages in safari or if I activate the multitasking bar, the animations are a bit slow with hiccups, sometimes, and all these with restore. What do you think I should do, stay on 5.0.1 , go to 5.1.1 or to ios 6 ?
