The SlingBox, the sweet little box that lets you watch and control your TV over the Internet, now works on fancy 3G cellphones. While before you could watch TV using the SlingBox on any PC or Mac connected to the Internet as well as on Windows Mobile smartphones such as the Motorola Q, this will allow you to watch TV on any phone able to connect to the high-speed 3G mobile broadband network. SlingMedia announced a partnership with 3, a company providing a 3G network in much of Europe, and the U.K. will be the first country to be able to use the SlingPlayer on their phones starting December 1st. Apparently we here in the States will have to wait 'til next year for that honor. If you're curious about the whole SlingBox thing, don't you worry — I've got a full review with all the details coming at you tomorrow afternoon, so stay tuned.
