Appstore account strange problem

[luistohe123]

I restored my 2g iphone with a custom firmware 3.0 that was already jailbroken and activated (before redsn0w was out) and everything was OK.
Suddenly I get an update in the appstore, about an app that I don't even have installed (AIM), and when I try to update it, it asks me for another guy's itunes account (never seen it before).

I guess the account came from the custom firmware, but i tried restoring the network settings, restoring all settings but the badge still appears. Ive tried syncing and nothing.

Im trying to find the file that contains the itunes account in the iphone, to delete it or modify it to delete the unknown account.
Anybody know which file is it?...

Sorry por reposting but does anyone know which file I'm talking about?

Just go to Settings, Store, and sign out. Then sign in with your own account.

Im signed in there with MY account, but the other one only appears in the appstore app and leaves an annoying badge...any ideas?

I have the same thing... I've also got a Skype update for an account that is not mine... Tried to log out and back in already, but to no avail! Anybody??
