Potential Problems:
- Facebook api rate limits, it looks reasonably high though?
- LinkedIn appears to be easy, but I’ve never seen an app use it, something fishy is up, SO comments saying 100x100 is best available
App Parts:
- Authorization Screen - auth with all networks and iOS contacts
- Processing Screen - show progress
- Results Screen - show contact name, then every avatar below in a row, allow tap selection of any 1 avatar per row
- Apply Screen - applies selected photos to contacts and show progress
