Apparently, tomorrow is national Nexus S day at Best Buy. The retailer announced via press release that they will be offering the “pure Google experience” phone free but for 1 day only at all Best Buy and Best Buy Mobile locations. At a price this good, it’s hard to say no. The deal applies to the unlocked GSM version for AT&T and T-Mobile, as well as the Sprint version of the device. Normally these kinds of deals are reserved only when signing a new 2-year customer agreement but you may be pleased to know that the offer is also good for those of you looking to upgrade a line as well.
