How can i update an ap uploaded on store ? should I recreate the App info from scratch ? only upload the new IQ ? is this the same in beta testing mode ?
When you log in to the app store and go to "Developer Dashboard" you'll see your apps. Click on one, and you'll see "Upload New Version", "Edit Details" and "Remove".
Build a new .iq file, and then "Upload New Version"
Also, when you are ready to switch from "beta testing mode" to "release mode", you do have to recreate the app info, as the two apps will be distinct as far as the store is concerned. It's as simple as generating a new app ID in the manifest (after version controlling / taking note of the old app I).
