Last time I reported on a Flash browser for iPad called iSwifter. However, Photon has replaced it as the best Flash browser for iOS devices.
iSwifter continues to have problems with slow connections and timeouts. This is probably due to overloaded cloud servers.
While Photon also uses a cloud browser infrastructure, response time is short and reliable. Another great benefit is that Photon is available for the iPhone, providing full-screen viewing pleasure.
One of the websites I tested this browser on was CBS.com.I played several Flash clips from "Big Bang Theory" and "Mike & Molly". They played smooth and seamless with no buffering.
The great performance and reliability of the Photon browser really makes it the browser of choice for iOS devices.
