Incoming: Google's New Android Phone

Buzz is building over Google's (GOOG) forthcoming Android powered smart-phone, from T-Mobile.

Crunchgear says it's confirmed the phone will be formally announced on September 23rd, and then released for sale in mid-October.

Meanwhile, in London, Google showed off pictures of a phone that looked very much like HTC's Dream, but had the branding obscured.

Google's entry into the cell-phone space comes as attention is shifting toward the advertising potential of the mobile market.

 "We can make more money on mobile than we do on the desktop, eventually," Google chief executive Eric Schmidt told CNBC recently.

The Web titan is already the most-used search engine on mobile devices, according to a new study. And wireless giant Verizon (VZ) is reportedly close to picking Google to be the default mobile search tool on its network.

The question for Google is whether it can make good on Schmidt's promise -- and turn your cellphone into a moneymaker.
