Tiny: no, I've used nothing but play/amazon. And the mobile app isn't NORMALLY listed. It popped up, and then it was gone. In fact, it looked like what JayJ posted, especially the pic.
On a related note, I use an HTC one v for a sort of media/mp3 player(it has android). The battery drainage was crazy in a way it wasn't before. Most of the used energy was " cellular standby", which elsewhere referenced a cell " radio". After turning on airplane mode it's fine, and the mobile data switch days it's off because airplane mode turned off the radio signal. Which is interesting, because I've never bought a phone plan for it, so the htc doesn't have " mobile data". So then when I see similar crap and power drain occur on my nexus 7 16gb, and smart quick settings insists the nexus has mobile data permanently on, I've got to wonder..
