Apple Thoughts: Citibank Fixes the Security Hole in Their Banking App

"Citibank has fixed a flaw in its iPhone app that was inadvertently storing customer account data on the mobile devices, the company said on Monday."

There is no problem here, move along. Well, there isn't a problem now, that is. Prior to Monday, they apparently had a glitch in their banking app, which caused some user information to be saved inside the app. This could have been exploited if it fell into the wrong hands. Namely, the hands of a hacker. So, if you are a customer you should have already been mailed a letter and advised...hopefully.
