I'm not getting the same result
My 180x180 png seems to be ignored and is replaced with a small image of the opening screen of the app (all white with a tiny camera icon at top)
Is it related to where the icon png is stored?
I assumed the icon is copied into the project at deploy time, uploaded to Volt and then included in the download into the iphone upon viewing fom the web, and it would be used to create the save to home page button
Instead, does the icon have to be accessable from the iphone location or volt location at runtime?
Are you running yours from volt or from your system where the icon would be accessable at run time?
I think we are getting close
