Greetings everyone, I wanted to ask a few questions about jailbreak and the newer iOS. 1. Is iOS 8.1.1 faster on iPhone 4s? I read about it online and it seems to say so, but (same as iOS 8.1) when I look up videos on youtube I keep seeing the newers iOS painfully slow when compared to 7.1.2 (I get it that the phone will never be as fast on account of new features and all... but is it THAT painfully slow, they seriously look impossible to use on daily basis, or are the videos just biased or something) 2. I've read a bit about SHSH blobs. If I have jailbreak on iOS 7.1.2, is it possible to backup the entire system so I can upgrade to 8.1.1 and in case I regret, downgrade it back to 7? 2.1 - what if instead of updating to iOS 8.1.1 I update to iOS 8.0 which I think is jailbreak'able? Thanks for the questions, I've never really had any issues on my 4s, but today (for no apparent reason) Safari, Mail, Weather and Calculator stopped working and are crashing whenever I open them... so I'm gonna have to restore my iPhone and loose some stuff (not important)... but this made me consider upgrading. Cheers!
