Nexus S with AT&T bands available in white for $600, headed to Fido and Rogers

It's been a long time in coming, but it looks like Google and Samsung's love child, the Nexus S -- a favorite around these parts -- is finally available with AT&T's 850 and 1900 MHz 3G bands from online retailer Negri Electronics, for $600 in your choice of black or white. It's not the first time we've seen the elusive Samsung GT-I9020A in the wild: it's already appeared both in the hands of the FCC and on the Bluetooth SIG's website. We've also seen pictures of a Nexus S with a white battery cover before. And here's more: we already knew the AWS version of the Nexus S was coming to Canada via Mobilicity, but according to MobileSyrup, you'll soon be able to pick up the Nexus S on Fido and Rogers for C$500 contract-free or C$100 with a three-year commitment, and these two carriers use the same 3G frequencies as AT&T in the US. So, until we hear something official from Samsung or Google, hit up our plethora of source links below.
