AT&T begins shutdown of AMPS and TDMA networks {Engadget Mobile}

Jun 22nd 2007 2:23PM Cingular bought the former AT&T Wireless for their 850MHz spectrum, since it is the sweet-spot for 3G and 4G goodies. They are forcing the TDMA users out of the spectrum. AT&T Wireless did similar many years ago when they went from analog to digital.

Don't be fooled by the comments about "no one is using TDMA" anymore...
