Siemens SX66 / MDA III / PDA2K (HTC Blue Angel)

I am having the same problems. I actually bought three bluetooth headset. The motorola 820 works awesome with it when it works right. The problem with the phone is that the chipset for the bluetooth is for 1.0 version. Most of the new phones use 1.1 version, I don't why Siemens miss this but it is very upsetting, I think there will either be an update or a recall, not sure how companies handle boothtooth software/hardware. Other then that the phone is freaken awesome. Also when you purchase your headset make sure it dont need compatible with 1.1. The 820 doesnt, so thats why it dont give any problems.
