Just in case you never got around to preordering your Samsung Galaxy Nexus on Sprint, you won't really have to worry about it any more. As noted on the Sprint website, they've already sold through their allotted preorder inventory and are advising folks to just pick one up on April 22nd in stores. That is, assuming you can find one. Anyone want to speculate what helped preorder sales? We have a small idea that certainly could have helped a little.
