OK update, I flashed CM 6 tonight and have the same issue with the Rom, not able to make a 3 way call, just to clarify in case peeps want to know my process, while on a call, I hit add a call, then type the phone number I want to add, then I hit call button, then I hear a dial tone and then silence the second counter works as I see the seconds moving, but nothing on the other end, if I wait or if I hit merge calls I get a fast busy signal and the call gets disconnected. So tonight I decided to flash back my stock rooted ROM to see, and low and behold, I am able to do a 3 way call, so it is something in Both Senseless ROMS that is not allowing me to make a 3 way call, any suggestions, I am all ears, I even spent 2 hours today with the developer of AOSP, and still no go, and also called Sprint to see if they could refresh the phone and still nothing, and no I did not tell them I was rooted, LOL
