We've see BBC iPlayer reach many devices over time, but it's been conspicuously absent on Windows Phone. Nokia has stepped into give us some relief, and it's now promising that a port of the TV catch-up service will be ready for your Lumia 800 "in weeks." Good news no doubt, although Nokia's encyclopedic knowledge of British TV streaming is also dashing hopes of using the Sky Go mobile app on Windows Phone anytime soon: the same Nokia rep doesn't see Sky being ready for a "good few months" at the earliest. As such, you'll have no problems keeping up with Doctor Who and Sherlock when they're airing, but we wouldn't count on watching live football matches for awhile.
Update: Pocket-lint is reporting that it quizzed the BBC over this issue and got a firm denial about a Windows Phone version, which suggests that The Inquirer's report, or its Nokia source, may have made an illogical deduction.
