T-Mobile USA has officially announced their Garminfone with a June 9th release through their website and select stores and authorized dealers.  Landing just in time for Father’s Day, the handset will be available for  $199.99 (after $50.00 mail-in rebate) with a new two-year agreement.

To help get things started, T-Mobile is kicking off a two-week Twitter sweepstakes which will see five Garminfones given away.  The  contest is called the ‘T-Mobile Garminfone Navigate Your Life Sweepstakes‘ and is already underway.   To enter the contest, Twitter users must follow @TMobile_USA and need to tweet at them with #needgarminfone in the body.  Let them know about a time when you were lost without GPS in 140 characters or less.   Entries must be received by 11:59 AM on June 9.  A full list of official rules can be found at http://ow.ly/1PPFr.
