Sign up page for the Samsung Galaxy S 4G is now up on T-Mobile’s web site

Previously rumored to being referred to as the Samsung Vibrant 4G, it seems that T-Mobile's next high powered device from Samsung will stick to the Galaxy S 4G moniker. And even though we're teased with the subtle outlines of the handset, its arrival on their web site means that we're going to see this bad boy very shortly in the near future. Right now, you can only sign up to receive emails regarding when it'll become available for purchase.
