So I tried to use my stereo bluetooth (Sony Ericsson MW600) for the first time with my new iPhone 5 today, but my iPhone 5 was just stuck on searching forever. What's up with that? It's also the first time I ever turn on bluetooth on the iPhone 5. I had no problem using the headset with my MBP or my old iPhone 4. Should I be worry or the headset is just not compatible with the 5?
