415233 story AT&T Wireless Network Is Open Too 122 Posted by Zonk on Friday December 07, 2007 @11:42AM from the me-too-is-fine-by-me dept. narramissic writes "Following last week's much-heralded announcement that Verizon Wireless would open up its network, AT&T is making it known that its wireless network is also open to outside devices. 'By its nature, GSM technology is open,' said Michael Coe, an AT&T spokesman. 'Customers could always use GSM phones not sold by AT&T on our network. We can't guarantee the performance of the device, of course.' AT&T will start to publicize that information through salespeople at AT&T stores, Ralph de la Vega, CEO of the company's wireless business, told USA Today."
