Ticketmaster Upgrades iPhone App For Ticket Buyers and Sellers

16% of the tickets sold by Ticketmaster in the first three months of this year were on mobile devices, and the process just got a whole ot easier. A new version of their iPhone app removes clumsy CAPTCHA login. And for the 60% of Ticketmaster venues that allow fans to use their phones as their ticket, that feature has been added in-app, as well.
