To make sure it's recognized as WGS84 datum/spheroid you should use
SetWellKnownGeogCS("WGS84") instead of SetGeogCS(...), and no need for
convertToRadians
Also, the arguments to SetGeogCS() are probably optional in your case
This might solve this problem and the other one you sent in another email.
