Melting bridges, misplaced landmarks and major cities disappearing: Apple's glitch-ridden maps program released in its new mobile software has customers fuming and analysts puzzled.

"Although #ios6 may say differently, we can assure you that the Tacoma Narrows Bridges have not melted," the Washington State transportation Department tweeted along with a picture of its hugely distorted spans on Apple Maps.

The new map program was released this week as part of Apple's iOS 6 mobile operating software, which powers its new iPhone 5 released Friday and can be installed as an upgrade on other Apple devices.

To the chagrin of many, the new operating system boots out Google Maps, which had been the default mapping system in Apple devices until now. And there is no Google Maps app yet for iPhone, although some reports say this is coming.

"Apple's made a new product that actually is pretty but dumb. Worse, they've used their platform dominance to privilege their own app over a competitor's offering, even though it's a worse experience for users," said Anil Dash, co-founder of the New York tech consultancy Activate.

Dash said that in trying Apple Maps, he was unable to locate the Bloomberg Tower in New York, and when he tried to find an address on Lexington Avenue in Manhattan, the program took him to Brooklyn.

"I'd tried the driving maps for everywhere from the New Jersey suburbs to rural Mexico and found out-of-date road information, impossible directions and a general level of unreliability that I never recall seeing from Google Maps, even when it first launched," Dash said on his blog.
