ISTR there's a requirement in the USA for newer 3G phones to be able to 
provide a position when an emergency call is made - this could be why 
the manufacturers are pushing this chipset, since it actually has a 
chance of being able to provide a fix while indoors. When used in this 
way it's not unreasonable to assume that the GSM cell data will be used 
to help with GPS positioning.
