PDF via Response.redirect or direct send does not work

Question

We have a web site which has a mobile section. We store some PDF's in a Database, retrieve them as needed and send the file to the client.
IT works fine on a desktop/notebook, iPhone. but on Windows Phone it just opens the reader, "downloads the file and says "Tap to open", but won't. Saving the file and doing a Response.Redirect doesn't work either.Only saving the file and setting
up a JavaScript href to do a location =
Will this be fixed, or do I need the workaround.

Thanks,
Never a problem in when NOT using phone. Always a problem when using phone (PDF Reader or Adobe Reader. The code that send it look like this:
Dim PDFContent() As Byte = objCmd.ExecuteScalar
objCmd.Dispose()
objConn.Dispose()
Response.Clear()
Response.ClearContent()
Response.ClearHeaders()
Response.ContentType = "application/pdf"
Response.Charset = String.Empty
Response.Cache.SetCacheability(System.Web.HttpCacheability.NoCache)
Response.AddHeader("Content-Disposition", "attachment; filename=" + FileName)
Response.OutputStream.Write(PDFContent, 0, PDFContent.Length)
Response.OutputStream.Flush()
Response.OutputStream.Close()
Response.End()
