iOS 9 is out today for your iPhones and iPads. It is fine, I’ve been running the public betas for a long time now, you could read Federico Viticci’s 23 page review for a second opinion. My favorite feature is that you can now block advertisements and tracking sites (they know what you do and decide to advertise socks to you if you visit a shopping site that sells socks, or just sell your browsing data) using any of a huge list of content blocker apps. I will be using Marco Arment’s Peace, which seems to have the best options and defaults. Unfortunately this will only work in Safari and the mini-browser you see within apps. It won’t work inside Facebook or other apps that have advertising within them, for example.
