Hi,
Does this REALLY need the qtquickcompat fix? If you replace "import QtQuick 1.x" at the start of your QML file with "import QT 4.7" like in this thread does the app still work? If so (and it worked with my app), you can remove this seperate step for installing it, and people who've kept their phones up-to-date as far as PR1.3 will be able to use it I think.
