3Abroad? Do you mean the 'Feel At Home' feature? That's not an app anymore, more of a service that is included and automatically activated when in one of the countries within the feature. As for the Auto Trader app, I've never seen one of those on any of the handsets I've sold. Though I know Three in Ireland runs separately from the rest of the UK, so there could be that. The only app that I've seen pre-installed on handsets is the My3 app which, to be fair, is actually pretty useful for letting customers keep track of their usage, as well as doing any general maintenance to their accounts, such as setting caps, etc.
