After the 2.1 upgrade my bluetooth cordless phone quit working. It will ring and it will dial out but I cant here anyone. This worked great on 1.5 before the upgrade. I talked to HTC and they said the stack was changed for bluetooth. Does anyone know a hack or a way to load the old bluetooth driver? I have read several other issues where it quit connecting to the car bluetooth. THis upgrade makes my 100 dollar cordless phone usless. I need it because my reception in my house is bad and I have to put it into the window to get service. Any help?
