It seems that the BBC's version of iPlayer for S60 has gone live, download it here. It has been implemented as a web runtime widget that kicks off streaming in RealPlayer. And it's also, naturally, a bit fussy about which devices it installs on. It seems happy with the N78, N95 and N96, obviously, other success stories welcome. Screenshots and more comments below...
The iPlayer application / widget opens a mobile version of the main iPlayer site. A number of shows are featured on the front page or you can browse for shows via channel or category. There's also a search function for tracking down shows by name.
