There's no need to post the same topic twice. Yes, to apply a patch, remove rsa first...as far as the delivery report, it's a seem edit and its in the successful seem edit thread in the bible.
the seem edit gives you the ability to turn the delivery report on, but the default is off so you have to set it to on for each message.
for default on, you need RSA removed and a patch. patch availability depends upon your firmware version.
