T-Mobile USA plans to begin selling the first smart phone powered by Google new mobile software late next month, according to people familiar with the matter, facing off against Apple's iPhone and Research In Motion's BlackBerry with a device that blends aspects of both. The phone's manufacturer, HTC, forecasts sales that are rosier than analysts' estimates. HTC says it expects to ship 600,000 to 700,000 units of the smart phone, dubbed the Dream, this year, a person close to the situation said Monday.

Santa Clara, Calif.-based Marvell makes GPS chips that go into cell phones and other gadgets. It said the deal will allow it to tailor products for high performance and low power consumption. Under the terms of the agreement, Marvell gains direct access to Trimble's GSP software and tools for development support and testing, Marvell said.
