> Synopsis:  Set Progressive Download Mode during Prepare
State 
> Previously, a feature was submitted for
"Progressive Download 
> Filesystem Plugin for Series 60 ". In that
feature, the 
> Symbian MMF plugin puts itself into "progressive
download 
> mode" in the AddDataSource method(), after a
"download ID" is 
> received via a CustomCommand. This would result in the

changes are made.

from

ensure 
> the CustomCommand is received first.
