How do I get an update to ios5 for my iPad2. ?
You can't. The only version available now is 6.
To upgrade to 6, plug your iPad into your computer with the USB cable and upgrade with iTunes.
You won't be able to go to iOS5. You will have to upgrade to iOS6 officially. There may be other sources on the internet that can walk you through but the official support answer is that you should be going to iOS6.
