I have the Skyfire app for the heck of it but just don't end up coming up againt Flash sites when I'm using my iPad, so I can't even report if it's made a difference for me. I'm out with my iPhone that has the data plan on it, so that has gotten over three , now nearly four years of me looking up things in iOS with no Flash. A handful of times it has come up while using my iPhone, but since with my iPad, (November 2010) I can't make a Flash dependent site emerge to save my life just to see. It obviously is based on whatever we all are viewing.
Have you tried one of the remote log in apps?
