The rumors about a Google-HTC combo for the official Android debut seem to be getting closer to reality now more than ever, after the Federal Communications Commission approved the sale of HTC DREA100 model, or HTC Dream, in the United States.

What this means is that T-Mobile can now carry on with its plans to bring the HTC Dream with Android OS in stores this fall, just in time for the holiday shopping spree.

The most probable launch date has to be around November 10, not October as it has been speculated, if we look at the confidentiality request asking FCC to keep details secret until November. Launching it earlier and requesting FCC to keep quiet for an extra month would of course be silly.

In addition to the HTC approval, Google is also making its move, by releasing a beta SDK which paves the way for the final Android 1.0 version. New features in SDK include many UI changes for 1.0, as well as a whole new set of applications (Alarm Clock, Calculator, Camera, Music player, Picture viewer, Messaging).

In addition to that, new development tools have been added, such as a graphical preview for XML layouts for users of Eclipse, as well as a tool for constructing 9-patch images. Furthermore, there is a new Home screen included, and a lot of bugs have been fixed.

The first rumors on HTC Dream with Android were reported by an unofficial T-Mobile blog, according to which the Android phone will become available this September (although new rumors give it an extra month or two), and will cost $399, or $150 for T-Mobile customers during the pre-sale week.

More details from Google, T-Mobile, and Google are expected to be announced as early as September, when the three are expected to make an official confirmation of the November 10 launch date.
