This one popped up earlier on Twitter courtesy of @evleaks. It's said to be the T-Mobile Curve 9315 - what it is or where it came from we have no idea. It does looks like it fits right in with the other recent Curves like the Curve 9350, 9360 and even the Curve 9310 - only with T-Mobile branding. Perhaps it's an upcoming prepaid device or just an addition to the BlackBerry 7 lineup. Regardless, there it is. We'll try to scrounge up some more info on this one soon.
