I have searched the internet and I know that in .Net we can use the following codes to ignore certification errors. ServicePointManager.ServerCertificateValidationCallback = new RemoteCertificateValidationCallback( delegate { return true; } ); But the certification classes are not supported in windows phone 7 development (know from http://social.msdn.microsoft.com/Forums/en-US/windowsphone7series/thread/4f795a8e-de05-4f01-be7f-0cf2be3a71c2 ).

According to http://msdn.microsoft.com/en-us/library/system.net.webclient.downloadprogresschanged.aspx , OpenFileAsync should have DownloadProgressChanged firing whenever it makes progress. I can't get it to fire at all. Fires fine with DownloadDataAsync and DownloadFileAsync instead though.
