T-Mobile USA will begin selling Garmin's first Android-powered smartphone--branded as the Garminfone--June 9. The smartphone will be available for $199.99 after a $50 rebate and with a two-year service contract. 

The release date is notable because it falls at about the same time Apple (NASDAQ:AAPL) is expected to debut its latest iPhone at the company's Worldwide Developers Conference. T-Mobile is trying to drum up interest in the Garminfone by kicking off a two-week sweepstakes where Twitter users will have the opportunity to win one of five Garminfones.

The release of the Garminfone is key for Garmin, which in partnership with computer maker Asus is hoping to parlay its successes on the personal navigation device front with an expansion into location-capable smartphones. So far, the company's success has been limited: Garmin earlier this year admitted "disappointment" in sales of its first smartphone, the nuvifone, which is selling through AT&T Mobility (NYSE:T) in the United States.
