Given the BlackJack's popularity on AT&T, it only makes sense that Sprint (among other carriers) would be looking to get in on that action. Indeed, as expected, Sprint has now launched Samsung's ACE (get it? like the really good card to have when you're playing blackjack?) that comes out swinging with Windows Mobile 6 Standard, 1.3 megapixel camera, microSD slot, stereo Bluetooth, EV-DO, and a SIM slot for hooking your globetrotting butt up with GSM service when you find yourself overseas; what it doesn't have is HSDPA, so don't look at this puppy as an apples-for-apples BlackJack II replacement. It's available now for $199.99 after the usual laundry list of rebates and contract discounts.
Separately, Sprint has also gone live with the M520, an unassuming slider we've known about for a while now with GPS, a 1.3 megapixel cam, and tethering capability. This one comes in at a reasonable $49.99 after rebate on contract.
