I'm new to the Treo 650 and I want to get a BlueTooth headset but I'm not sure which way to go. My phone has BlueTooth software version 1.0 but all of the headests I've found are 1.2 or higher. I don't really care about music or any of the other stuff, I just want to be able to use it as a headset. Is there a way to upgrade the BlueTooth software on my phone, or should I just get a headset and hope it works?
