I'd be happy to help. If you have registered your copy of Programming iOS 5 you should have been sent a 40% upgrade discount for print books and a 50% upgrade discount for ebooks when we publish a new edition. The print version of Programming iOS 6 is estimated to be released March 2013. The ebook version of Programming iOS 6 is available, and to make up for the discount code not being sent to you I have put the ebook into your account. Have a great day!
