Stop new iOS auto-download on iPad I noticed some weird traffic pattern on my internet connection, tracked it back to my iPad, after some tinkering I finally realized that my iPad is downloading iOS 6.1 on it's own!!! I didn't ask for it, and there's no button or obvious means to stop it. For now, I've disabled the WiFi; but seriously, this is terrible, how do I stop it?

The device: iPad 2 - running iOS 5.1 - No intention to upgrade anytime soon
In short, you can't stop the download once the OS has been told to download it.

First of all, I highly suggest you update to the latest iOS version because developers are constantly dropping support for older iOS. As for how to stop auto updates, after 45 minutes of searching, I think I found a solution. Doing this will also disable automatic downloads. 

Here is what you (or others in your situation) can do:
Navigate to General > Store on your iPad. Next, turn on the switch that is labeled "Use cellular data". That will help most, but in your case, you mentioned turning off WiFi - so if you are concerned about that bandwidth, you'll have to keep networking off until you get to a network where bandwidth or cost for traffic isn't an issue.

This doesn't actually stop the download permanently, but will tell the OS to not burn your data plan and wait to complete the download over WiFi. Now, your phone will retain that downloaded OS image until such time as you erase the device and restore from a backup (where the download is not backed up and will be lost) or apply the update.
