I would assume that this is a problem with the Bluetooth stack inside
the phone. There could be also a bug inside our RFCOMM layer. I don't
know, because I can't test it. Bluez <-> BlueZ connection are performing
at full piconet speed.
To really track this down I would need an UMTS phone and a flatrate like
internet access from an UMTS provider.

Marcel
