We’ve heard about Galaxy S variant with a physical keyboard and it looks like its gearing up for the US release. The phone has been pictured with Sprint branding and in addition to its evidently 5-row keyboard, the Galaxy S Pro notches up on two other fronts than the Galaxy S.
First is the LED flash for camera, which is strangely missing for a powerful phone like Galaxy S and secondly, it supports 4G network. Apparently, Galaxy S Pro will be the second 4G phone for Sprint after HTC EVO that went on sale recently.
As far as other features are concerned, Pro is claimed to be pretty much identical to Galaxy S.
