I chose to update from 5.1.1 to 6.1 from the Settings app. Right now, the iPad only displays the picture that says I should connect it to iTunes. After I do this, I get a dialog box "iTunes has detected iPad in recovery mode. You must restore this iPad before it can be used with iTunes". I understand this procedure erases all data and customizations, and that's clearly not what I'd want to do (it's like having to destroy the house if you just want to paint a few rooms). Is this a part of a an iOS upgrade nowadays, or is there any way around it?
