According to the new announcement from XperiaBlog, the Sony ST25i Kumquat will be highly likely to be renamed the Xperia U during its launch, which is still yet to be determined.

Currently, the handset is rumored to feature a 3.5-inch display, a 1GHz dual-core processor, and a 5MP rear-facing camera. We’re looking at a possible international release here, by the way.
