Restore missing Contacts

If after updating to iOS5 it appears that all your contacts have vanished (like mine did) try this...

Go into Contacts

Click on the Groups button at the top left of the screen

Select All Contacts

Your contacts should be visible again (mine were)

It appears that none of the filters (All, Business, Family, Friends, etc...) are selected after updating so nothing is displayed althoough they are still there. Obvioulsy selecting All shows then again.

Hope this works for you.
