T-Mobile's Accessory Roadmap leaked: HTC HD7 mentioned
There are two schools of thought on this. One has the accessories coming after the actual device hits the market. This would have the HD7 landing on shelves late October. The other has the device and accessories landing at the same time which puts the Windows Phone 7 device on shelves early November.
Either way, that holiday season target date that was set by Microsoft way back in February is still looking really good.
