What have they done with 'plane mode' in Jelly Bean!!
I was just finishing off setting up my desktop on my new phone last night and was putting in place my final toggle widgets (wi-fi, bluetooth etc.) and got stuck on trying to get a plane mode (switch off everything bar display) widget that I knew I had. It had simply vanished. It turns out that Google have removed this feature for developers! You can still 'have' plane mode by going to Settings-Wireless and Networks-More-Aeroplane mode (convenient huh?) but cannot now get an app that will toggle this from your desktop (or any app for that matter).
Why on Earth do they think people don't want this?! Then I found this from the Google dev community. It seems they are not too happy either: Issue 40497 - android - Bring back the ability to toggle airplane mode, or a way to enable/disable the cellular radio without affecting other radios - Android - An Open Handset Alliance Project - Google Project Hosting
It annoys me when manufacturers break things for no valid reason.
