I also have the same Alltel new ROM issues with 10secs and back to the speaker, but i have also noticed another issue. When I press the headset button the phone will come on the phone app starts, then the new voice dialer starts. I can say home or whatever tag i set but the phones mic is picking up my voice. Its not going through the headset to get here. If the phone is in my pouch on my side this isn't going to work. After the call starts the mic on the headset works. Why wont the headset pickup voice prompt instead of the internal mic? I too like the new ROM but this BT issue makes me want my old one back.
