Re: As long as they run a 3G service ...
I'd bloody well hope they're killing off 2G; setting phones to disable 2G entirely by default (which won't happen while 2G is in use) makes it more difficult for any rando to run an IMSI catcher. They haven't yet taken it out behind the barn because of all the fielded devices that have a 2G-only modem and need to be upgraded. (ATMs, soda machines, whatever—not all being so easily accessible, of course.)
