According to this pic snapped by a source to TmoNews, it seems some T-Mobile stores are starting to receive new accessories. Namely a generic sleeve “for 10 inch tablets.” There’s a couple ways to interpret this, the simplest way is that T-Mobile is simply carrying many accessories and cashing in on customers that already own one of the many 10 inch tablets on the market. T-Mobile’s own tablet lineup currently consists of the 7 inch Dell Streak and 8.9 inch LG G-Slate. Of course we’d like to believe this is a sign of things to come and T-Mobile is planning on carrying a 10 inch tablet in the near future such as the Galaxy Tab 10.1. But then again, they may just decide to start selling WiFi-only tablets in an effort to push their mobile hotspot hardware. It’s really hard to tell from a generic accessory, but if hardware-specific accessories start appearing, we might be headed in the right direction.
