Quick question: Those of you that have tried it with your and found that it works well, are any of you using a 8700g on T-Mobile?

In 2 years of using Bluetooth-equipped BlackBerries, I have yet to find any brand that works as well as Motorola with my s. But I desperately want a headset that cancels noise like a champ! So, I'm hoping someone has tried the Jawbone® with an 8700g on T-Mobile so I can know how it performed. I'm still open to the idea of trying another manufacturer if and ONLY if it's proven that they'll give me what I want! Plantronics and Cardo Systems have both failed me, will Aliph be the first manufacturer to actually succeed at beating Motorola for compatibility?
