Ok... I have one PDT WM 6.5 so I guess i will be testing with that one 
... but If I didn't have one, is there a mechanism to test the App as there was with ATE? or ATE is not used anymore?
Another question: the customization of the App can be done with eclipse juno with agentry editor plug-ins for this versión (IM 4.0)? or they must be done with the SDK?
BR,
MC
