I talk about the the "Verizon Patch" earlier in the FAQ.

"How do I apply the Verizon Bluetooth patch (hack) to the Sprint (or other earlier released phone) and what does it fix?"

The HBH-300 and 600 are the only headsets I see claims of working with no claims of problems.

One person said the patch fixed his headset issues but I don't think he mentioned which one he had.

I'm optimistic that the patch will help the headsets with mixed results.

For a headset to be claimed as working it should not get static or disconnect in the middle of call.
