Micromax had recently launched Qube x560. It features WiFi connectivity, which was missing in qubex550, along with GPRS.
The new Qube has a capacitive touchscreen with a 3.2 inch display. The battery has been reduced to 1000mAh from 1200mAh for making it even lighter and as opposed to a single button on the Qube the new one will feature a three button interface, two for call connect and disconnect while the third key is for selection.
The pricing has been kept quite similar to the older Qube and the phone will retail for Rs 5200 approximately.
