The Sony ST21i "Tapioca" is a rumored mid-range Android device with Ice Cream Sandwich. It is also said to feature a 3.2-inch HVGA display, an 800MHz processor, 512 MB of RAM and a 3 MP camera.
We expect the device to hit the streets around July for about €150. Definitely a budget phone, but it comes with Android 4.0.3, which could make it much more enticing.
