AT&T today announced that it has reached an agreement with Sprint that will allow AT&T to sell AT&T-branded wireless service using Sprint's CDMA network. The five-year deal will make AT&T a Mobile Virtual Network Operator (MVNO), similar to Virgin Mobile, which also uses Sprint's network. The new service is planned to launch later this year, after Cingular completes its acquisition of AT&T Wireless.
Sell up your GSM network and jump on to a nice CDMA network... nice!
