Mike - Does anyone Know if a dual 1800/900 frequency phone is any advantage in CDMA. There are three different bands/modes of interest to Qualcomm in the US: 1) PCS - 1900MHz CDMAOne - Coverage limited to cities and highly travelled routes. 2) Cell CDMAOne - 800MHz - I think the coverage is generally even worse than PCS CDMAOne although I haven't actually checked recently to see how many AMPS cell providers have switched to CDMAOne. 3) AMPS (Analog) - 800MHz - Available almost everywhere, but a real battery hog, and with limited services available. The 2700 series (1900 CDMAOne/800 AMPS) has the advantage of using PCS when it is available, but gets all the coverage of AMPS. (It's a pity there is no 2700 series thin phone.) I don't think that currently a 1900 CDMAOne/800 CDMAOne phone exists (??) but if it did, given the limited coverage of 800MHz CDMAOne, I'm not sure how useful it would be. JMO Clark PS This is all off the top of my head. I have never actually done any detailed research on 800 MHz CDMAOne coverage, so take it with a grain of salt.
