By coincidence I looked at my mobile applications folder today and discovered seven supposed app that had no reference to an app name shown in iTunes: LUHL.ipa TLZE.ipa PNDU.ipa XSDJ.ipa EZAT.ipa MUTG.ipa QMWP.ipa They were all created/modified on the same date and time in 2010. They are no apps that I ever downloaded or installed. What are these? Do you want to check your iTunes>Mobile Apps folder if you have similar strange things in there? Also there is no mention on the web of these things.
