Apple is taking action against sites selling early access to the iOS 6 beta, according to MacStories. To install the beta, people must technically be registered under Apple's $99 annual iOS developer program. That fee, though, lets people configure up to 100 separate devices. Some websites have been selling UDID activations to the public, typically at a cost close to $10 per activation; that can make the scheme very lucrative, since a site only needs to sell 10 activations per account to recoup expenses, and some have been selling many times that number.
