latest 10.1-inch Galaxy Tab alright, not to be mistaken with its thicker 10.1v sibling that's gradually rolling out across Europe and Australia. How can you tell? Well, the older Honeycomb tablet bears the GT-P7100 codename, whereas this FCC filing and a Wi-Fi Alliance certificate show off the GT-P7510 moniker for this WiFi-only 10.1. Oh, and the drawing of the backside -- pictured after the break -- is a dead giveaway, of course. What remains unknown is the mysterious 1GHz dual-core CPU inside this razor-thin slate, but given the release of this FCC application, it probably won't be long before all is revealed.
