MetroPCS Communications is getting its first Windows Mobile 6.1 OS phone with today’s release of the Samsung Code for $299.99.

The Samsung Code comes with the Microsoft suite of tools including contacts, calendar, tasks, notes, voice recorder and Windows Live. An optional WizPro interface allows users to customize their home screen and create shortcuts to the most frequently used features on the phone, including missed messages, calendar appointments and more.

With the Samsung Code, users can access work and personal e-mail through direct push e-mail and other messaging options, according to a press release. The phone synchronizes with any computer via Microsoft Outlook Mobile through ActiveSync technology, which can be installed by using the CD included in the box, USB cable or downloading over the air. Once the device is synched, users have instant access to e-mail, contacts and calendar. Corporate and personal accounts can be synced with Microsoft Exchange Server.

Other carriers have started rolling out phones with Windows Mobile 6.5 OS, an interim step to Windows 7, which is expected in the first half of 2010. The Samsung Intrepid from Sprint uses Win Mo 6.5.

MetroPCS shares have taken a beating in recent months as competition heats up in the prepaid space. Last week, Walmart said it would start selling $30 and $45 Straight Talk plans in more than 3,200 stores nationwide. Straight Talk is the result of a partnership with TracFone.

MetroPCS shares, at $7.04, were trading slightly down in early trading today.
