It’s getting hard to keep up, with the BBC rolling out new versions of its UK-only seven day Internet TV catch-up service on what feels like an almost monthly basis. This time iPlayer support has been added to a whole bunch of recently released mobile phones.

First up is the Nokia N85, which will utilize the version currently available on the N96. As you may remember from my recent review, unlike the iPhone and iPod touch offering, iPlayer content on the N96 (and now N85) isn’t restricted to streaming but can also be downloaded for viewing off-line for a limited period.

Secondly, two Windows Mobile-based smartphones, the Samsung Omnia and Sony Ericsson Xperia X1, can now access iPlayer through a new mobile-optimized website. And next week, the brand new Sony Ericsson C905 will also be added to the list, a notable first as the device is a so-called ‘feature phone’ not a higher-end smartphone as such, although those distinctions are becoming a little outdated as technology gets cheaper. As well as on-demand content, the new iPlayer mobile site also provides live TV and radio streaming.

“These phones have been selected as they hit our requirements of Wi-Fi and 3G support with great browsing and media playback experience i.e. the video and audio look and sound good”, writes the BBC’s Jon Billings, Head of Technology for Mobile.

More handsets are promised in the future, including “one or two more future Nokia devices”, says Billings. Nokia N97 anyone?
