Apple is looking to shrink or wipe out waiting lists for the iPad and iPhone 4, and soon, a source in the company says. Apple Stores regularly maintain "Priority Lists" that reserve devices for people in the order that requests were made. While these also serve the purpose of telling Apple how to manage production, some stores now allegedly have as many as 250 to 750 people on hold for iPads, and 500 to 1,500 waiting for iPhones, leaving many potentially unsatisfied customers.
