MobileBurn have published their review of the HTC S710 Smartphone ‘A power button can be found on the top of the device, the camera shortcut key on the right, and the volume and voice memo buttons on the left. An extUSB jack, an HTC version of microUSB used for charging, data connections, and headsets, is on the bottom, and a microSD memory card slot is on the right of the device, each protected by the best litter rubber covers I have seen. The covers are robust, yet easy to remove. The positioning of the microSD slot on the top portion of the slide did make it a little hard to put a card in though, as you need to hold the device closed in order to apply the force necessary to insert the card. The SIM card slot can be found on the back of the top portion of the handset, and can be accessed by sliding the device open and unclipping a small door. Quality abounds here.’
