Touche. I just tried updating Google Maps using the Play Store to see if it was just you having the issue. But I got the error "Package file was not signed correctly. Uninstall the previous copy of the app and try again."
On another note: like he said as well, aside from that and the bugs you're working out (the lockscreen buttons), everything is running smoothly. Thank you very much for this ROM.!
Yes, I'll have to work on a fix for that too. That happens because when you modify system files too much things stop working and you need to "sign" it to have Android accept the apps. I'll be working on it, expect new version with both bugs fixed anywhere from 2 days to a week.
