看来不需要了，无法定位是因为越狱，已找到解决方法。

I have released a Cydia package that fixes the location services issue caused by the Spirit jailbreak.

1. In Cydia, add the source http://cydia.pushfix.info/

2. Install the package "iPad Location Services Fix"

That's it. It restarts locationd on install and on every boot after the SpringBoard finishes loading. You should have no more problems with location services after install.
