for those who want to try other bluetooth dongles other than the
recommended ones, here are others that also worked.

but too bad, i now got 4 dongles from 2 different stores, far more
expensive than the one's from deal extreme, all generic with CSR
bluetooth chip. worse, all 4 dongles have same bluetooth address. all
4 have 00:15:83:15:A3:10. thus giving me a bluetooth name IOIO (A3:10)
when it is detected by my phone.
now i can not try 3 IOIO with bt simultaneously, the phone just
displayed 1 detected bluetooth device. even if 3 IOIO is powered up.
guess i just have to wait the ones from dealextreme.
