Your phone is not different from others, it's only different iGO app version.
Yor iGO app is Avicsync and has different data folder path.
You should never change folder name (rename) of your iGO installation.
It is not only global_cfg that could not be found, but complete program structure. This file is only the first that program is looking for.
You can only change path to your iGO installation inside Weather NextGen app as explained in first post.
