I would like to add to this that, while it's not desirable to have  
the tools and SD image on your
phone, it is possible. When I found out about the SD-based method, I  
was surrounded by Macs
and my nearest Linux system with an SD-card reader was either in my  
pocket or 7K miles back home :)
So I cleaned out some stuff on my GTA02 and was able to download the  
SD image onto it and dd that onto the
uSD in my FR and reboot. The flashing procedure was successful and  
now all my SIMs work.
