Earlier this week, an image of Sony’s upcoming ST25i “Kumquat” smartphone leaked onto the Internet. The Android-powered device is rumored to feature a 3.5-inch qHD display with a 1GHZ dual-core processor and 5-megapixel rear camera. It is also rumored that the handset will debut at next month’s Mobile World Congress in Spain. According to a document found on the website of Indonesia’s telecom authority (similar to our FCC), the ST25i Kumquat is listed as the “Sony Ericsson Xperia U” —  although by the time it is officially unveiled, it will likely drop the Ericsson label and be known simply as the Sony Xperia U.
