Just want to update that XXJVU is much better for me. Had it on now since overnight and this morning and reception is outstanding. Goes to 2G when it should and doesn't hold 3G with only 1 bar.
XXJVU modem radio is sweet.
I am curious though does the KF1 also have the 2G bug when you enable 2G only and then go back to 2G/3G auto does it stay stuck on 2G?
