Hi Desert Flyer,
That is correct. When you download a update package from our website, you will notice the TFR and Metar box is automatically checked. This way at the time of download, you have the latest TFRs and Metar data for the entire US. You can update your iFly from your Home, Office or even most FBO's. That is what I do so I have the latest TFR and Metar data just prior to flight. Of course, you always want to contact "flight briefing" prior to flight in the event of any pop=up information.
