hazytodd was one of several readers to tip news of Sprint Nextel's plan to grab a piece of the iPhone action in order to halt the company's downward slide. According to a Wall Street Journal report, Sprint has committed to buying 30.5 million iPhones over the next five years (summary of paywalled WSJ story), which at retail rates works out to roughly $20 billion. "To sell that many iPhones, Sprint would have to double its rolls of contract customers, convert all of them to the Apple device or a combination of the two." A separate rumor at Boy Genius Report suggests the iPhone 5 may be a Sprint exclusive until sometime next year, with Verizon and AT&T getting the upgraded iPhone 4S until then. Apple is holding an event to unveil the new phone tomorrow.
