you have to remove the shielding cover and replace the 1800 band filters
with footprint-compatible 1900 MHz filters.  It's possible, but requires
good SMD soldering skills and access to the right parts.

You can also remove the filters completely.  This will hovever
significantly degrade receiver performance in the presence of
out-of-band interferers.
