WHY aren't voice & "3G" cellphone frequencies simply updated with SOFTWARE for switching carriers??
For example, when switching a GSM device from T-Mobile to AT&T...
Or a CDMA device from Verizon to MetroPCS....
Or, when a carrier buys a new range of frequencies - like MetroPCS did in NYC....
This SHOULD all be a "software update" and/or settings...
Why isn't it?
