T-Mobile unveiled the Galaxy S Relay 4G from Samsung on Thursday, the latest in the Samsung Galaxy line, which will be offered exclusively by the carrier.

It’s powered by Android 4.0 Ice Cream Sandwich, and leverages T-Mobile’s 4G (HSPA+ 42) network. T-Mobile is really touting the business features of the phone.

“The Galaxy S Relay 4G is also a SAFE (Samsung Approved for Enterprise)-designated device that offers a full portfolio of enterprise-ready features and capabilities,” says T-Mobile. “Samsung SAFE offers comprehensive IT Policy support for top-tier mobile device management (MDM) solutions, on-device AES-256 bit encryption, and enhanced support for Microsoft Exchange ActiveSync, as well as integrated support for a range of virtual private network solutions.”

It has a ful 5-row QWERTY keyboard and 1.5-GHz Dual-Core Qualcomm Snapdragon S3 processor. T-Mobile says this enables business customers to quickly view and edit documents and share files. It has Wi-Fi Calling and support for Smartphone Mobile HotSpot for up to five devices (with a qualifying plan).

It has a 4-inch, Super AMOLED screen, a 5-megapixel rear camera, a 1.3-megapixel front-facing camera and 720p HD camcorder (1280×720) resolution. It comes with T-Mobile TV in mobile HD2, which lets you watch live TV, as well as Samsung Media Hub for renting and buying movies and TV show.

“Consumers are increasingly looking for a powerful device that makes it easy to integrate their busy work and personal lives,” said Andrew Morrison, vice president of product management, T-Mobile USA. “The Galaxy S Relay 4G is the perfect addition to T-Mobile’s popular Galaxy smartphone lineup, providing our customers with a reliable and business-centric Android experience — and the easy access to entertainment for which Galaxy devices are known.”

The Galaxy S Relay 4G will be available nationwide at T-Mobile stores, and other select retailers (and at T-Mobile.com, of course) in the coming weeks.
