The first Google phone, based on the hotly anticipated Android platform, will be unveiled at an event in New York City later today.

Deutsche Telekom’s US mobile unit, T-Mobile USA, will be the first carrier of the device, which is expected to be made available to the public in early November.

There’s a holding page up on the website for today’s event, which suggests the handset will be branded as the T-Mobile G1 with Google, although the source code for the site makes mention of the many other names that have been bandied around recently – Dream, Kila, Google Phone and GPhone specifically.

Whatever the name, the unit is sure to be a rebadged HTC Dream, which was recently approved for use in the US by the FCC. Documentation submitted by HTC to the regulator asks for confidentially on some of the details until November 10, which may point to the gadget’s launch date.

The Dream’s operating frequencies of 850MHz and 1900MHz WCDMA mean it could be used on AT&T’s network as well, but it looks like the rest of the world will have to wait for another build of the device with support for more/different frequencies.

Last month, the Open Handset Alliance, which is tasked with developing the platform, lifted the curtain on Android 0.9 SDK. “The APIs are now pretty stable and we don’t expect any major changes,” between 0.9 and version 1.0 which will ship on retail handsets,” the OHA said.
