There's a new Sony Ericsson in town, and it's not the X10 for a change of pace -- this time, it's a mysterious device known simply as the "U5i." That certainly follows SE's classic naming convention, but what might give us the best clue is that the Satio is known as the U1 and the Aino as the U10 -- in other words, we're probably looking at a full-touch handset of some sort. Coincidentally, Cellpassion had previously dug up a user agent profile for a U5i, calling out a 640 x 360 display, 2 megapixel cam (what?), and Symbian -- so if those numbers pan out, we might not be looking at a "Satio killer," so to speak. Then again, we've also seen the U5 model number associated with that 8.1 megapixel Kurara, so it's anyone's guess what's really going on here until we see something official. At any rate, it's interesting to be distracted momentarily from the company's Android efforts; Symbian might have some life left in it after all, yeah?
