A couple of days ago, EA released in the appstore NFS Shift for the iPhone and iTouch. As always , with this games, we lack the money to customize / buy cars. Well, how does $6M sounds,is that enough for you? If that is the case, you’re in luck because there is a patch for that in Cydia.
All you need to do is to add this repo in Cydia : http://repo.beyouriphone.com . Now go to “Changes” and install the patch. That’s it. Enjoy the new cars and all the customization you want.
