This is the big Mobile World Congress week, and expect lots more of these announcements: Nokia (NYSE: NOK), which bought online photo, audio and video sharing service Twango last year for a reported $100 million, has renamed it “Share on Ovi”, using its Ovi multimedia brand, reports PCWorld. This is the first consumer-facing Ovi branded service launched by Nokis since it introduced the brand last year.

The Ovi site already includes Nokia’s music download service, available in UK, Nokia’s mapping offerings, and it mobile gaming platform N-Gage.

Meanwhile, on the now-off-now-on N-Gage, it has started opening it up to users again: it invited users of its N81 phones to download a pre-release version of the N-Gage app and start buying and using games on their phones. The new platform was supposed to launch late last year but has been delayed till now.
