Also expect it to take forever to download off iTunes. When we went to iOS5 I remember it taking about 2 or 3 hours to pull the file and install because everyone was trying to update.
As recommended by many sites, make sure you have your power source nearby once you begin downloading iOS6. The last thing you want happen is to lose your battery in the middle of the download.
Great question! Apple began the official rollout of iOS 6 on Wednesday September 19, 2012 just a couple of prior to the release date of the iPhone 5. For more info regarding this update please visit http://www.apple.com/ios/.
