According to some legit-looking shots from a Sprint forum, this is your new Samsung Instinct Mini.
It's really not looking so different than the original Instinct, save for the rounded edges that should make it more comfortable in the hand while distinguishing it a bit more from the iPhone. If earlier leaks are to be trusted, you'll see this handset sometime in mid-April. But is anyone out there earnestly excited about the redux? [Sprint Users via BGR]
