If you want to find out how your software will run under 1.1.3 and the SDK, I recommend you test it out under 1.1.2 or 1.1.1 as user "mobile". First, consider where all your resources will be located (in /var/mobile rather than /var/root). Next, start thinking from a ~mobile perspective. Issue a "sudo - mobile" from the command line and test how your software runs from the "mobile" user perspective.
