Samsung has released promo videos for both the Samsung Captivate and Samsung Fascinate, which are heading to AT&T and Verizon respectively. We already know the pricing for the Captivate: $199.99 on a new, two-year contract after a $100 mail-in rebate. It's set to launch on July 18th. Unfortunately, Verizon hasn't said anything about the Fascinate's pricing or release date. The commercial itself is really brief and pretty self-explanatory, and is actually the same exact video we showed you about the Samsung Vibrant, for T-Mobile. Just showcases the physical differences in the devices, while the "main gist" of the videos is exactly the same.
