Xperia Tipo, that is also named as ST21i Tapioca in Taiwan, is the upcoming smartphone from Sony after the launch of its Xperia U and S series. Sony Xperia Tipo is already available now only in Taiwan and is about to be launched soon few more countries.
It seems now all major brands Samsung, HTC and Sony are now concentrating to make smartphones with Andorid 4.0 itself and no other operating system. Anyways, talking about Sony Xperia Tipo ST21i, it is a mid range Android ICS based smartphone powered by 800 Mhz MSM7227 processor. The device also seems good for gaming as well because it features a Adreno 200 GPU.
As mentioned above that it is a Mid Range device, Xperia Tipo has just 3.2 inches touchscreen display that offers 320 x 480 pixel resolution. There is a 3 MP that offers only VGA video recording and there is no LED flash as well. Not sure but it seems like there is no Front camera in this device. Anyways Xperia Tipo seems to be very good and reasonable smartphone for users.
There are many sources that claim it as dual sim smartphone, but am not sure about it yet. Also there is no official announcement on pricing and release dates.
