Jailbroken Ipad & App Store Apple ID

[darkflea]

A friend of mine just jailbroken his Ipad, The Ipad has already had an Paid apps installed but on a different ID and a paid app on her ID.
so what is happening now is the if she's trying to update the app with a different ID, instead of the different ID pops up her ID pops up instead, even if she removes her ID in the store settings...... any clue what is happening? and how to resolve it. Thanks
