Comments on: AT&T's Network the 'Most Open?' Yeah, 'Most Open' to the U.S. Government http://digitaldaily.allthingsd.com/20071206/att-open/ by John Paczkowski Sun, 22 Nov 2009 21:52:19 +0000 http://wordpress.org/?v=2.8.4 hourly 1 By: Kevin T http://digitaldaily.allthingsd.com/20071206/att-open/comment-page-1/#comment-910 Kevin T Fri, 07 Dec 2007 00:40:49 +0000 http://digitaldaily.allthingsd.com/20071206/att-open/#comment-910 I'm not sure what the big deal is here. Cingular and T-Mobile use GSM-network phones, which means you can slip in a SIM card, which is programmed with your Cingular or T-Mobile phone number, into nearly any GSM phone(it has to be quad band capable i.e. 850/900/1800/1900 Mhz) and start making phone calls. Maybe it's just us tech-types, but that's been common knowledge since the Stone Age. I’m not sure what the big deal is here.
