According to an anonymous source, Apple's iPhone will soon be sold at Wal-Mart. Boy Genius Report's insider says that sales will begin on November 15.
The truth or falsity of this claim will be a nice litmus test of either (a) how far retailers will go to accommodate Apple, or (b) how far Apple will go to conquer the world. Wal-Mart typically demands heavy compromises from its suppliers, including control over distribution and packaging. For Apple to agree to this would go far beyond demonstrating that it never wanted to be a "cult," or that it has no interest in maintaining an elitist image: it would mean the hot breath of The Other America on the back of Steve Jobs' neck.
More likely is that Wal-Mart has simply agreed to take iPhones the way Apple sends them, as Best Buy does, (and remember, Best Buy had to retrain staff and sell at close to cost, hoping to profit on accessories), or that the rumor is bogus.
