I am on CM10. Not able to keep a strong signal though. Still haven't seen 3G. Goes from 4G to 1X and back. Setting is set to LTE/CDMA prl
I would recommend flashing back to stockish ics and documenting the signal there. CM10/AOKP don't mess with the radio so I don't think your signal issues would be caused by that... but thats just my thoughts.
