On Monday the Wall Street Journal reported a glitch in the mobile banking app provided by Citi for iPhones which makes the sensitive information to be stored on the devices or PCs. After this report Citigroup Inc provided a statement where it said that the glitch had been fixed.

Citi spokeswoman Natalie Riper said on Monday its U.S. Citi Mobile iPhone banking program may have also saved account information on personal computers that customers hooked up to their phones.

Customers of a largest US lender were recommended to install an upgraded version of the application which deletes any information that may have been inappropriately saved to the iPhones or PCs. The upgrade is available from Apple's App Store or iTune store.

"We have no reason to believe that our customers' personal information has been accessed or used inappropriately by anyone," Riper said in a statement. "There has been no data breach."
