Not sure if the obvious is missed...
- If you are trying to update a cracked app, NO IT won't threw itunes/appstore/etc...
- If your free apps you downloaded from your account are not updating, chances are they where free for a limited time and now have a price tag and since you got for free don;t qualify as purchaser...I've run into a few of these
- as for wrong email address, its from the crack or person who purchased it...... same as if you load someone elses apps on your phone with there login password, you need to keep using there login/password for updates or will fail..can't use your own.
- if the email is associated to phone and itunes ( synced ) will need to use its password.....I had a few issues with used iphones and had to get devices unauthorized from original owners account before I could sync/setup with my own, as they have synce with 5 pc's and could not sync anymore.
- try disabling icloud backup of apps, as may have cracked app in icloud and defaulting to force update
