Hi Ron,

The reason you have to buy a dual-mode handset is that the entire network is not using a single backward-compatible standard, rather frequencies are dedicated to each standard in proportion to revenues, which vary by location.

WCDMA uses 5 MHz channels, GSM 200 kHz channels, so what you are calling '*Truely* backward compatible' is not in the definitions.
