Not entirely sure if this is the correct section to post this in, but seeing as I'm here now... I was wondering, if I have an official release of a game already installed on my iPhone, and a developer has asked me to beta-test a newer forthcoming pre-release version of that same game, can I install the beta version alongside the official version? Or can I only have one or the other? Second part to that same question: if I can only install one, then will the beta wipe out any progress I have made in the official version and knock out all the saved levels I have cleared? Or will it retain all my data? Any help appreciated... Thanks.
