title: Change ALL numbers in Address Book / Contacts
body: <p>I'm trying to give a uniform change to all the numbers in my address book, I want to add my country code (+46) to all number starting with 0 and thought I'd make an app for this. The question is how to do this in the best way, it seems kind of - hard.</p>
  
  <p>The usual way seems to be through a person picker: <a href="http://developer.apple.com/library/ios/#documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/Chapters/UI_Controllers.html#//apple_ref/doc/uid/TP40007744-CH5-SW4" rel="nofollow">http://developer.apple.com/library/ios/#documentation/ContactData/Conceptual/AddressBookProgrammingGuideforiPhone/Chapters/UI_Controllers.html#//apple_ref/doc/uid/TP40007744-CH5-SW4</a> - but this means the user has to pick the contact that it wants to change, which must be an overcomplicated way of doing this.</p>
  
  <p>Is there a way to loop through all the numbers in the address book, change them/it, and then put them back?</p>
  
  <p>Thank you in advance, Tobias Tovedal.</p>
