Bluetooth is a very useful technology, but it can be a real PITA to set up and troubleshoot. I'm having fits trying to get my headset to stay connected to my phone. Currently, I can't even get them paired consistently. Naturally, the headset is about 2 weeks out of warranty. So, is it a bad headset, a problem with the phone's hardware, a glitch in my recent Android upgrade? Do I have a clue? Heck, I guess I really wanted a new headset anyway.
