have you tried it without JBX?? I was having some bad issues with JBX a couple builds ago. I tried JBX on a couple different builds of this ROM and I just didn't have good luck with it. I would get random freezes like you forcing me to restart. A lot of times when opening the dialer to make a call or whenever an incoming call would come in it would freeze up and I couldn't see who was calling or answer it. The soft keys would light up, but the screen is just black and wouldn't do anything forcing me to go through the restart process. Very annoying when at work and I needed to call our dispatch or operations control... especially when I have to borrow my first officer's iphone that worked.
after re-flashing the ROM and not installing JBX it has worked just fine the last couple weeks. I honestly can't remember the last time I had a freeze up, restart, or any problem really with this after removing JBX. Going to flash 3.6 here in a minute, we'll see how that does.
