How Does T-Mobile's Samsung Vibrant Measure Up?

The Samsung Galaxy S Vibrant is on sale at T-Mobile stores starting Thursday, July 15. What sets the Vibrant apart from other Android handsets?

Samsung and T-Mobile held a small launch event for the Vibrant the other night in New York City. Since Samsung is selling four versions of the same phone with AT&T, Sprint, T-Mobile, and Verizon Wireless, I asked T-Mobile what it was doing to make its version stand out from the pack. The answer? Software and services.
