Good to hear I'm not alone. But unfortunately I'm still looking for a solution.I selected the italian language, still the caller's location is shown in chinese.
Did you manage to fix it, somehow?
Maybe we should look into replacing the Dialer.apk from a clean CM10.2 ROM in the system/app folder? Do you have any experience with that?
Edit:
Just read this: http://forum.xda-developers.com/showthread.php?t=2163974
Seems very easy to make a CWM flashable zip to replace the Dialer correctly.
