How to block iOS 9 accidental/automatic upgrade

Hi!

Just to get the word out for you people how are furious about those sneaky downloaded iOS 9 upgrade files on your apple devices and don't want to upgrade now or ever.

Block at DNS-level: mesu.apple.com

This will block iPhone/iPad accessing information about iOS upgrades.

Be blessed - spread the message!

Some details about the domains in question:

mesu.apple.com - Apple's Mobile Asset Software Update service. Provides an XML file with information about available iOS updates. When blocked, devices cannot determine that a new update is available.
appldnld.apple.com - (Optional) Apple's iOS and software repository. Where devices will actually download the iOS update from. However, other software and updates are also provided by this URL. Blocking may not be desirable in all environments.
