awhile back i even believe i saw something that says they had too much and had to give some up when purchasing at&tws.
if im correct they only needed some out on the west. cingular has affiliates as most carriers do. so those smaller affiliates will bid (and win) and lease their spectrum to cingular or whatever carrier.
now if cingular pisses any of these affiliates off and they seperate then cingular has to either purchase that spectrum from them, rent from another, be @$$ed out, or wait until more spectrum becomes available to bid on or purchase.
dont quote me but i believe that's how it was explained to me.
hope this helps.
You also have to take note that perhaps they bid on some spectrum but were outbid by others and decided not to take any action to win the spectrum back.
