    Ok, where to begin.....first I had an older bluetooth headset the worked till I dropped it in the sink...this is where my journey begins. So I head to BestBuy and purchased the Motorola H12...after 3 hours of charging it paried no problem but anytime I went to make a call while on UMA/Wireless (T-Mobile) the call dropped and went to SOS. I had to then reboot the BB and it did the same thing!

    Took it back and got the Plantronics Discover 925, it worked with UMA but didn't have the function for voice dailing :--( So back to BestBuy I went.

    Now I have the Jawbone 2, exact same issue with the Motorola H12, will not work while on UMA/Wireless only works when on GPS/EDGE.

    This is becoming very irrating!! At home I get no signal so I must use UMA and the same goes for the office....I need a Bluetooth Headset that works while on UMA. My older one (Which they no longer make) did the trick but now I cannot find a replacement.

    Has anyone else had the same problem? Is it my BB? Is the Bluetooth? I am up for any suggestions. I have already done the "Pull The Battery" trick and still will not work! I am at my wits end!! Any help or suggestions would be deeply appreciated!! Thanks!!

    I have exactly the same problem!

    Tmobile, Jawbone II, won't work with UMA/wi-fi.

    If you are comfortable enough with the operation of your BB, I would suggest upgrading the OS.

    Okay. I just bought the 8820. Silly me, I assumed Tmobile would have sold me one with the current OS on it. Further, I would assume the Tmobile Support would have mentioned that I needed to upgrade to the current version. Oh well.

    You already have the newest official Tmobile release. AT&T has a newer OS released you can install.

    I should give you this for reference too: Proper Upgrade / Downgrade Procedure

    The upgrade took some time, but it was worth it. The Bluetooth headset is working with UMA. Calls start on UMA and go to EDGE when I walk outside and the call signal strength decline, then switch back to UMA when I reenter the house.

    I'm thrilled that my 8820 is now working as I imagined it would when I ordered it. Good that it does because last Monday my office landline was ported to the 8820!
