You have 16 GB in the internal SD. It is not enough? Why everybody wants to move everything to the external sd? I mean, this is not a Nexus One with almost no internal storage. Working for me flawlessly. I've created the pack, tested, write installation instructions and then uploaded, and in my SGS2 it works with every single apk and skin provided within 800x480 folder. But I do not insist on moving everything to the SD. Instructions are completely detailed in .txt file inside each folder as well.
Maybe, we copy to SD card because the instructions ask to do it !
The instructions.txt file says "copy license folder to "your SDcard route/iGO/". "
I think the author means "path to SD card root/iGO".
But by doing such, and on my ZTE Blade (800x480px, 300 MB internal app partition), I have same missing files errors as others.
We continue with Copilot, Navigon and... Google Maps.
