HTC Dream Starts Pre-Sales September 17th?

The rumors of a delayed Android have been debunked by a newer rumor that the HTC Dream, the purported first Android Device, will be available for pre-order on September 17th. As in only a skip and hop away September 17th. The details from TmoNews state that the presale is only for current T-Mobile customers who will have to pay (a measly) $150 to own the latest and greatest phone on the market. New Activations are currently unknown, TmoNews expects those folks to have to wait for the national release (around October).
Though this rumor may be true, one of the odd nuggets is that activation requires a Gmail Account (wha!?). We at Android Central don't see how that ties in.
