Earlier today the Sprint Nexus S 4G became official, and not long after that Best Buy announced that it'll have retail exclusivity on the device, and that the presale will begin today. This means that other than a Sprint store, Best Buy will be the only place you'll be able to try and purchase a Nexus S 4G. As we all know, Best Buy has had many retail exclusive releases lately, one of which was the T-Mobile version of the Nexus S, which they were very excited about.

“The exclusive launch of Nexus S from Google was a landmark for us and it continues to be one of our best-selling devices,” said Scott Anderson,head of merchandising for Best Buy Mobile. “Bringing Nexus S 4G to our stores is one more way we’re making it as easy as possible for people to find the phone that’s right for them.”

The Best Buy presale is a $50 fee, that is applied to your purchase at the time it is made, and can be done at any Best Buy retail location, or any Best Buy Mobile stand-alone store. [Best Buy] More in the Nexus S 4G forums
