Google plays safer with Nexus S and T-Mobile.

"Nexus S will be welcome to developers and truly cutting edge Android users who do not want to tolerate the uncertainties of carrier updates every time an OS upgrade appears. The phone will run the upcoming release 2.3 or Gingerbread, and a Google UI without carrier (or Samsung) overlays and preloads. It will offer a first look at some new features such as built-in video chat and native VoIP, plus some new gaming capabilities, according to reports. It might even be sold via Google's online store, as well as TMo, again, though this was the aspect of the strategy that most annoyed operators - but according to GigaOM, Andy Rubin, VP of engineering, says the company is still interested in selling unlocked phones via its own shop."
