Was the E815, then it was the KRZR, no since both are EOL'd now.....i think it is probably (unfortunately) the LG 8600, or the RAZR v3a. Once the new RAZR 2 comes out I fully expect that to take the title. Those are the handsets.... The smartphones almost all get better rf though, except the treos. The 6700 is also a little iffy in some places.
