I am trying to install the same app twice on the same iPhone, does anyone know if this is possible? I have searched and found a few tutorials but I have not found one that worked. I can get it to install but it crashes when I try to open it. I have an iPhone 3gs with 3.1.2. Jailbroke with blackra1n. The reason I want this is because there is an app that is a single user app and will not run on my wife's 3g, so we both want to have access to the app with our own log in. There is not an option to log out and in with different user. The only way to change log in is to delete the app and reinstall, then log in with different user. Any help with this will be greatly appreciated.
