Whether or not you’re a fan of T-Mobile’s secret “projects” (with the most recent being the long-speculated Project Dark that brought some interesting plan options to the carrier) they probably interest you just as much as the biggest magenta fanboys themselves. A new project name is being thrown around – Project Emerald – and this time it looks like it focuses on a specific device.

A source of TmoNews’ states that the project will bring T-Mobile a “new Nexus One-like device” that’s going to be sold and marketed by the carrier both online and in stores. There is one phone that immediately comes to mind that fits the bill of a Nexus-like device: the Samsung Galaxy S. It’s been rumored for a while to come to T-Mobile, now, and this could be a small grain of hope that the rumors turn out to be true. Of course, more Nexus-like would be an HTC Desire which a couple of smaller regional carriers in America are already getting.

Or it could be something totally different. No one knows, but we’re going to keep our eyes glued to the scene, in the mean time, as we hope to lay any information we can find out onto the table (hopefully this month as a TmoNews commenter reminds us that Emerald is one of the birth stones for May).
