iPad launch guide before it, Best Buy's iPhone 4 launch plan has just made its wily way into our collective lap, replete with loads of details on how your favorite blue-shirted electronics salespersons are going to be spending their Thursday morning. While we've yet to see any hot scoops inside its two dozen pages (aside from some confusing, contradictory gibberish about whether Best Buy will have iPhones at launch at all) we have learned that stores will open up previously suspended preorders on launch day, accepting reservation fees for devices that customers can pick up at a later date. What we're not seeing here is anything about specific number of units, but there are various lines that caution against expecting much in the way of non-reserved phones -- should there be any, the guide advises first come first serve once the store opens. In other words, it's business as usual: call ahead and show up early. See some choice quotes from the playbook after the break.
