It looks like the Sony LT22i Nypon will be known as the Xperia P when it launches later this month at the Mobile World Congress in Barcelona, together with the Xperia U (ST25i Kumquat) and an unidentified phone codenamed Pepper.
The phone, according to a report from GSMArena, which should go on sale from April onwards, will cost around 370 Euros and should turn out to be a smaller version of the Xperia S.
Other unconfirmed features include an ST-Ericsson NovaThor U8500 dual core Cortex-A9 based chipset, a WVGA capacitive display, Wi-FI, Bluetooth and a camera that's inferior to the Xperia S.
Sony Ericsson - which will soon lose the Ericsson name - is likely to retire a few of its smartphones which were launched last year at MWC.
They all ran on a single core Qualcomm Snapdragon system on chip and shared a few common specifications including the screen resolution.
The Xperia arc, the Xperia Play, the Neo and the Pro were complemented later in 2011 by a new set of smartphones, like the Xperia arc S and the Active. Expect prices to fall; the price of th Xperia Play already took a plunge last year reaching £150.
