you could always use a european band version and do the filter re-work.
After that, the phone should work in all bands, as there are no band
filters anymore.  Of course the phone will be sensitive to out-of-band
interference from other strong transmitters, but apart from that it
should solve the difficulty obtaining US-band versions of the phone.
