Looking for medical attention? Don't use the iOS 6 Maps app. A search for hospitals in San Francisco returned this map result, labeled with the red and white cross symbol denoting medical services as the "U Csf Medical Center & Ucsf Children's Hospital" at 1855 Folsom Street. The phone number on the listing called the UCSF Women's Options Center on Sutter Street in San Francisco. The operator there knew of no medical services located at 1855 Folsom Street.
The same location at 1855 Folsom Street in Google Maps is labeled as the "UCSF Mission Center Building", and when I called the phone number listed there, I got the voicemail for the "Mission Center Building's Night Custodial Supervisor".
