I apologize of this is not too technical, but please bare (bear) with me? This is for just in case! And only if you find it absolutely necessary!
THIS METHOD MAY NOT WORK FOR EVERYONE, PLEASE DO SO AT YOUR OWN RISKSo for anyone that for any reason wants to go back to MF 2.1.1 from 3 you can. The catch is that you should have a backup of MF 2.1.1 in iTunes on your computer first.
I have 2 iPad 2’s. One had MF 3, the other 2.1.1. I had backed up all my apps on the one with 2.1.1 in iTunes on my laptop. I deleted MF 3 on the other iPad. I connected this one to the laptop, opened iTunes and synced both devices. I scrolled to the apps that I had backed up from the other iPad (MF2.1.1). I dragged the MF 2.1.1 app to the iPad’s desktop, waited ‘till they synced once more, disconnected my iPad and viola, there was the app I had just dragged over.
I opened MF and there you are, version 2.1.1 was successfully copied from one iPad to the other. It works perfectly. The only downside is that all my scenes were gone on the “copied to iPad” But they are alive and well on the original iPad with 2.1.1. And as you know once the original iPad is docked in the DL and you connect wirelessly with the other iPad, you are given the choice from where you can use the stored scenes. Select the docked iPad and your scenes are "magically"
sent to your “blank scenes” iPad” Now you have your hard earned scenes on both devices.
If you only have one iPad, you will lose your scenes completely, but you can roll back to 2.1.1 if you have to.
PLEASE NOTE THAT THIS PARTICULAR DL IS STILL ON THE V2.1.1 FIRMWARE
