Steps to reproduce:

2. Go to Address Book
3. Next to 'Number' text box, hit the blue (+) button.
4. Crash.

If you 'Ran' the app, you will have to re-open Application Output to see the trace.

App is still getting crashed by tapping on + button from the address book.This issue still exist with both device and simulator also.I have attached screen cast for the simulator

#Fixed in push: 0817cdf

- We had some missing error messages for the user. Now the user has to select a contact first end then, will be able to edit it or add new phone numbers. With the previous solution we tried to add info to a null contact (not selected by the user).
