guys a few more data points for DUN rates. these are all gsm phones in a umts network in the US (at&t). htc tilt 580kbps lg cu500 600kbps samsung sync 320kbps moto razr v3xx 550kbps I believe the tests were all using a bt1.2 adapter on one side or the other so the lg for example might be hitting a throughput ceiling for bluetooth. -- Brad
