Another day, another Linux mobile platform launched. The latest flavor hails all the way from China Unicom -- Apple's sole iPhone partner in China thanks to its WCDMA network -- who's just announced the WoPhone platform to, ironically, "break up the foreign smartphone platform monopoly." Of course, this isn't the first time that a Chinese carrier has pushed out its own OS -- TD-SCDMA operator China Mobile already has OPhone, though it's really just a bastardized Android; whereas China Unicom claims that WoPhone's an entirely new OS built around the Linux core. That said, some of WoPhone's UI elements do look awfully familiar.

While we don't expect to see this new OS trickling out to the rest of the world any time soon, a big handful of manufacturers -- namely Motorola, Samsung, HTC, TCL, K-Touch, ZTE, Huawei, etc. -- and cloud service partners were present at yesterday's launch event to show off the first batch of devices, including the K-Touch U2 pictured above.
