In offering its own OS, S amsung unveiled the 3G HSPAequipped Wave, a fulltouchscreen phone whose open Bada platform enables third-party developers to create applications that can be downloaded through a Samsung store.

For its part, SonyEricsson showed its second phone with HD-video recording. Like the full-touchscreen Vivaz announced earlier this year, the Vivaz Pro features 720p HD-video recording and playback, VGA video output and Symbian S60 smartphone OS, but the Pro adds a slide-out QWERTY keyboard. Both models come in versions that operate in 3G HSPA mode in the U.S. 850/1900MHz bands and in the overseas 2100MHz band.

The Mini and Mini Pro are smaller versions of the X10. The X10 and X10 Mini are full-touch models, and the X10 Mini Pro adds slide-out QWERTY keyboard.
The Xperia X10 was due in the U.S. in the first quarter, the company previously said. The Mini and Mini Pro are due in unspecifi ed markets in the second quarter.
