While you may be tempted to install the recently released beta version of iOS 7, you may also be worried that it could brick your iPhone. Never fear: 9to5Mac points us to a new demonstration program from consumer electronics website Recombu that lets you preview iOS 7 without any risk of wrecking your device. How does it do this, you ask? By hosting the entire thing inside your web browser. While this obviously doesn’t give you the exact same experience as actually using iOS 7, it does give you a nice look at the new user interface and lets you see how the redesigned core iOS apps look. 9to5Mac notes that “if you’re using Firefox or Chrome, you can also use your webcam to take pictures in the Photos app.”
