This well kept secret surfaced just recently. All Apple devices running iOS 7 have a pretty darn well hidden Easter egg. Just follow this step-by-step instructions carefully and the very first Mac OS version 1 will appear on your iPhone or iPad. How freaking awesome is that?
This is how you add your favorite websites shortcut to your iPad or iPhone running iOS 7. It's a really useful feature if you are accessing some webpages frequently.
You are trying to install or open an app that didn't come from the Mac App Store but you got a message saying App can't be opened because it is from an unidentified developer. This is how you bypass it.
In case you just upgraded your iOS powered device to iO7 or any other version and now this device runs slower than it used to, this resetting of the device procedure might speed things up.
If you are accessing certain websites very often with your Android powered Samsung Galaxy S2, I suggest you to add a bookmark shortcut to your phones Home screen.
