iCloud - Turning on/off process problem
Anyone stumbling across this entry might be interested in the solution mentioned in this Apple Support Community entry (https://discussions.apple.com/thread/4314429?start=0&amp;tstart=0):

Excerpt of the solution:


  In the settings app, go to iCloud and turn notes off.
  
  Next, scroll down and select "Delete Account". Choose save data onto phone.
  
  Re-activate the iCloud account on your phone (you'll have to type in your password)
  
  Turn notes back on.


Seems a bit radical at the first glance but it worked perfectly for me.
