I know it’s funny to post your iOS 6 Map Fails to the Amazing iOS 6 Maps Tumblr, but could you also go ahead and report the problem to Apple so they fix that shit in the future?
To report a problem, tap the bottom right corner in Maps. Tap Report a Problem. Follow the Directions.
Don’t just be snarky, help fix it.
But then post it to the tumblr, because public mocking does help, unfortunately.
