HTC recently announced its dual-SIM Desire 600 with Sense 5 on board, but there was no word on the availability of the smartphone. The Taiwanese manufacturer might launch the Desire 600 smartphone along with the rumored Butterfly S on June 19, if these press invitations that appeared online are the real deal.

The HTC Butterfly S is said to be a slight upgrade over the current Butterfly with the device sporting a 5-inch 1080p display, UltraPixel camera, microSD card slot and a higher capacity battery.

We already know the specifications of the HTC Desire 600, but to recap its features, the device sports a 4.5-inch Super LCD2 display with qHD resolution, 1.2 GHz Snapdragon 200 chipset with Cortex A5 processor, Adreno 203 GPU, 1 GB of RAM, 8 megapixel rear camera and a 1.6 megapixel front shooter.

The Desire 600 comes with 8GB of inbuilt memory, Android 4.1 Jelly Bean, 1,860mAh battery and a wide range of connectivity options that include Bluetooth 4.1, NFC and GPS.
