Sony Ericsson ST25i "Kumquat" has emerged in a spy photo and it looks, well, quite familiar. The upcoming smartphone looks a lot like the highly anticipated Sony Xperia S flagship, which got announced at CES this year. Its specs however, have been toned down a bit.

The device is rumored to feature a dual-core CPU, clocked at 1GHz and a 5MP snapper. The screen is reportedly in the 3.5" range, and has FWVGA resolution.
