GRASS 5.3:  m.proj2 -i

GRASS 5.7:  cs2cs + `g.proj -jf`
(cs2cs is from PROJ4)

see:  http://article.gmane.org/gmane.comp.gis.grass.devel/4013


also in 5.3, s.in.garmin for Garmin GPSs will automatically project +
transform sites. I haven't finished updating v.in.garmin yet for
5.3 or 5.7 but they're mostly there..
