Dave,

I know Verizon talked of dual mode phones before (?Samsung) but an  
Indian carrier is reportedly coming up with not only a CDMA/GSM dual  
phone but also a GSM/GSM Phone.

The latter is something I've wanted for a long while, but (US)  
carriers hate the fact I would rather put in a different SIM when  
traveling instead of roam.  This is part of what I call the "Bill of  
Materials" Manifesto (write-up forthcoming) - it doesn't cost that  
much more to add in hardware (or functionality) that consumers want,  
but market power and other reasons prevent these from happening.  
Examples include adding SD card slots to music players, adding  
standalone GPS functionality to phones, allowing a phone to be used  
as a modem (esp. via bluetooth) etc.
