Sony Ericsson has just announced two new Cybershot phones and a Walkman phone which, in all likelihood, will be part of their lineup at the Mobile World Congress. More specifically, the C903 and C901 Cybershot phones and W395 Walkman phone have been unveiled a week ahead of the grand event in Barcelona.

Unlike the Hikaru, everything’s official with these phones. The C903 comes with a 2.4-inch QVGA display, 5-megapixel autofocus camera with dual-LED flash, quad-band GSM/GPRS/EDGE, dual-band UMTS/HSDPA (900/2100MHz) or tri-band UMTS/HSPA (850/1900/2100MHz), A-GPS, Stereo Bluetooth, TV-out, 105MB internal memory, and Memory Stick Micro expansion slot. From what we heard, the C903 is the very same model that was codenamed Frances in the past.

The C901, formerly referred to as the Filippa, is pretty much the same with the C903 albeit lacking the dual-LED flash, TV-out, and A-GPS. In place of the dual-LED flash is a Xenon flash, and it’s expected to be released in emerging markets only. We can't find the official press release for the C901, but if you want to know where we got this info, its from USEB. Granted that both phones belong to the Cybershot family, you can expect a bevy of imaging features to be included in these phones.

Meanwhile, the W395 is the new Walkman in the group. It’s a slider that features a 2-inch 172x220 pixel scratch-resistant display, 2-megapixel camera, Bluetooth, quad-band GSM, and motion gaming support. Targeted at music lovers, the built-in speakers with high quality bass should be a welcome treat as well as the other other multimedia enhancements that come with W395.

Both the C903 and C901 are expected to become available in Q2 while the W395 should be available anytime soon as it’s scheduled for a Q1 release. Pricing isn’t available yet, but we’ll probably soon find out next week once they take center stage at the MWC.
