This is pretty cool.  The downside is that 2.3 is only available on
the newest Android phones right now, and counting on a speedy upgrade
of a 2.2 handset to 2.3 is risky.  Getting one of the Google phones
(Nexus One, Nexus S) would make timely and continuing OS upgrades more

If you run a voip program on a pre-2.3 Android (and I don't know if
it's different on 2.3 or not, though I'd assume it works with the
built-in SIP) you won't be able to use a bluetooth headset with your
voip program.
