	Domestically, yes.

	Not only are you dependant on Sprint if you go that route
(Verizon is already pulling the plug on CDMA this year.), it was never
any better than +/- 10 ms or so.  You can get that via NTP pointed at
the Internet.

	At best, all you were doing with CDMA was relying on a cell 
site's GPS receiver and holdover characteristics -- which were totally
opaque to you.  At least you can monitor NTP.
