Gizmodo : Cingular Sony Ericsson Z500A in Stores: "Cingular is sending out notices to customers that the Sony Ericsson Z500A phone should be available in stores. I don't see it on the Cingular web site quite yet, but if it's in stores for purchase, it should show up online soon enough. The Z500A is a EDGE clamshell with push-to-talk features that Cingular has been pushing pretty hard. Let's hope it lives up to the hype."
