Sony Ericsson Z500

This phone is available from Amazon.com in a presale with a $200 rebate from AT&T and a $100 rebate from Amazon (you make something like $125 with your purchase with a plan). Last I heard it was available through Cingular? There is even an add in this month's "Lucky" magazine for the phone showing the z500 saying 'the phone shown is available exclusively from Cingular'.. Hmm.. 😕
