The almighty awesomeness known as “Ryan Petrich” has recently wen’t to work on peoples aggression and hatred towards Apple’s new Maps app. He was able to get the Google Maps app from iOS 5.1 to run on an iPhone 3GS that is running iOS 6.0.
Part of the description of his video -
Still crashy and cannot be distributed to the public yet, but it mostly works
The good news is, he may be able to get Google Maps to work on iOS 6. The bad news is, that may be further away then we think. The video simply shows that it is able to be done but still needs allot of work. When awesome jailbreak devs do awesome things for grumpy people, it makes me very happy to be a part of the jailbreaking community.
