We heard earlier last week about a future T-Mobile press conference scheduled to be held on September 23rd. The Wall Street Journal has confirmed it. And it appears that indeed the main event of the conference will be the announcement of the G1, the first Android device in the history of the universe.

WSJ also says that the Android device will be launched in October despite delays. HTC and T-Mobile are going to deliver on time what is expected to be a great handset. Will it sell? I heard T-Mobile has great plans for the HTC Dream as it will ship anywhere from 600,000 to 700,000 units to be sold after official release.
