Usability 
Fifth Third Bank is a major regional banking corporation operating in Ohio, Kentucky, Indiana, Michigan, Illinois, Florida, Tennessee, West Virginia, Pennsylvania, Georgia, North Carolina and Missouri. The bank's mobile site provides an ATM and branch finder and allows you to view your account balance, account summary, and recent transactions. Fifth Third Bank is the first site to go live with a two character .mobi domain name. Two character names, which are considered highly desirable, were recently made available by dotMobi. If you are fancying a two character dotMobi for your site they are available for "free" after payment of a $500 processing fee. Details on the DotMobi blog.
