It looks like the Symbian Smartphone Show is shaping up to be a bit of a showdown betwixt placeshifters today, with both Sling and Sony announcing Symbian support for their respective products' players. Unlike Sling, which announced both UIQ and S60 versions of its SlingPlayer Mobile, Sony is only going as far as UIQ support for its LocationFree on the wings of its fresh P990 smartphone -- a very Sony-like (read: proprietary) move, considering Sony Ericsson isn't down with the Nokia-backed S60 platform. Odds are Sony would've liked to have cut a version for its smartphones a year or two back, but the P990 is the first phone in the P series to rock data fast enough (via UMTS and WiFi) to handle the heavy-duty bandwidth requirements LocationFree -- or most any other placeshifting tech, for that matter -- requires. Sony Ericsson's claiming immediate availability of the Symbian client, though it's not yet live on the P990's download site. Of course, a LocationFree player doesn't do much good without the device itself, and a US version of the P990 is nowhere in sight, so just keep on toolin' around with those PSPs until further notice.
