Just like all other major US carriers, Sprint is already taking pre-orders for Samsung's Galaxy S6 and Galaxy S6 edgesmartphones. Thankfully (for customers who just can't wait until April 10, the handsets' official release date), Sprint will start shipping the new Galaxies this Monday, on April 6. Right now, Sprint allows customers to pre-order only the Black Sapphire and White Pearl versions of the Galaxy S6, while the S6 edge is available in Black Sapphire, White Pearl, and Gold Platinum. There's no word on when, or if the carrier will also sell the Green Emerald and Blue Topaz variants. What about pricing? Well, Sprint is offering the Galaxy S6 32 GB for $199.99 on contract and $648 off contract, the 64 GB model for $299.99 on contract and $768 off contract, and the 128 GB model for $399.99 on contract and $864 off contract. The Galaxy S6 edge costs $100 more, and it looks like Sprint isn't offering the 128 GB model. Both the Galaxy S6 and S6 edge are also available for $0 down with Sprint's monthly leasing plans, as well as with the carrier's 24-month Easy Pay program.
