Apple may quit Google Maps and add an in-house mapping system on the upcoming iOS 6 operating system, according to rumors. The 9to5mac.com blog reported that Apple may develop a new mapping application by taking advantage of its acquisition of Placebase, C3 Technologies and Poly9.

Apple's own mapping application will appear on iOS 6, unnamed "sources" told the blog.

iOS 6 is expected to be announced in June at the Apple World Wide Developers Conference.

Apple has not commented on the report.
