Loading up a 3rd party browser like Skyfire just to watch the occasional Flash video isn’t an ideal solution, and Frash seems to have hit a dead end. HTML5 is starting to replace Flash on many major video sites, but it’s far from ubiquitous.
iOSFlashVideo is a simple bookmarklet that allows users to view Flash videos from Vimeo, MegaVideo, Flickr, DailyMotion, Break, and Blip.tv (with support for additional sites coming soon) from within Mobile Safari. It’s unclear how exactly this bookmarklet works, but there doesn’t seem to be any server-side rendering or conversion taking place. My guess is that it’s forcing the video site to load the corresponding HTML5-ready video, instead of the embedded Flash version. (See, many sites support both Flash and HTML5 videos, but sometimes it can’t auto-detect the browser being used, so it loads the incompatible Flash version by default.)
It seems to be a hit-or-miss for most users, so don’t expect too much. Nevertheless, it’s completely free, so try it out and let us know how it works! Installation instructions can be found on the homepage.
