DataWind's no stranger to making inexpensive tablets (India's Aakash immediately comes to mind) but to date its products (including the iconic PocketSurfer) have only featured 2G connectivity -- in addition to WiFi, of course. This appears to be changing with the Ubislate 3G7, an unannounced 7-inch, 3G-enabled tablet that recently sauntered through the FCC. According to the test reports, it supports quadband GPRS and tri-band HSPA (2100 / 1900 / 850MHz), making it compatible with AT&T "4G" in the US. Little else is known about this mystery device beyond what's outlined in the FCC documents. From what we've been able to gather, it features WiFi b/g/n and Bluetooth 3.0, a microSD card slot plus front and rear (2 MP) cameras. Follow the source link below to check it out for yourself.
