Subject ios commit: Fixes #CB-828 Use blocks in contact.save
Date Thu, 23 Aug 2012 18:09:33 GMT
Updated Branches:
  refs/heads/master 242837e48 -> 1a0dcb7ae


Fixes #CB-828 Use blocks in contact.save

Used simple blocks to wrap the search and save functionality.
Somewhat limited in use of blocks since must guarantee that
ABAddressBookRef access always occurs in same thread (per Apple docs)
