I'm now back to stock iOS 5.1.1 on both my iPhone and iPad. Using Absinthe to jailbreak was very easy, but I don't think I'll be missing anything from the jailbroken side of the fence. I liked having AppSliders and Zephyr on my iPhone, but none of the other tweaks I installed were good or stable enough to stay on my device for more than a day. As for my iPad: well, it sat there with Cydia installed, but little else. So I restored both devices last night because I simply didn't need anything that the jailbreaking world is currently offering, but also because I encountered a few strange bugs along the way. There was the occasional Springboard crash and some weirder stuff, like Safari and Cydia simply refusing to load unless I soft reset my device.
Not all jailbreak experiences will be like mine, but I don't want the extra headache of having to troubleshoot these things any more…especially not when the stock firmware does 90% of what I want.
