I have used LFY, Project Elite, Lithium Mod with various kernels and while I am on the phone it just turns off or completely reboots itself. The CPU temp goes WAY up when talking on the phone but not other apps. I tried switching to Dialer One from stock just to see but that is even worse. I have some important calls coming up...votes for the most stable ROM regarding phone function (crazy that IS what the phone used to be for!).
