If you have an iPhone, I have found that the Sandisk Mini works well for getting the latest weather, TFR's, and monthly updates.
The Mini works by downloading from the phone then use the USB to update iFly.
I've found downloading from the iPhone works better with Firefox.

You will have to use the Create an Update Package and download the zip file to the root of the USB drive to update on the iFly.
