We’re still waiting for Dell’s Looking Glass tablet to arrive and now (what should be) the device has paid a visit to the FCC, which has approved its integrated 3G chip for the UMTS bands II, IV and V, hinting compatibility for AT&T and T-Mobile. Approval for Bluetooth 2.1 + EDR and Wi-Fi b/g/n was also part of the deal. The reports show an SD card slot along with a SIM card slot, the latter which will definitely be used to channel data into the device. There isn’t any confirmation if this device will support voice calling just yet, though. With CES just around the corner, we’re hoping Dell has some juicy announcements for us.
