var polygonInGeoCoords:Polygon = WebMercatorUtil.webMercatorToGeographic(myGraphic.geometry) as Polygon;
Check out the WebMercatorUtil class. It should help you.
There is a sample linked on the page also..
If that does not work you are going to have to 'project' the geometry using a Geometry Service...
Glad to hear it worked out.
