If you’re a Sprint Premier Customer (ie, anyone who owns a smartphone with them, which most of you on Sprint reading this blog probably do), you may have seen an invite in your inbox sometime yesterday to pre-order their version of the Samsung Galaxy Tab. We don’t have a date yet, but you can pre-order it for $399.99 (after rebates and a two-year contract). You’ll be required to add a new line with a data-only plan: $29.99 for 2GB per month. Neato! Go ahead and hit that pre-order button in the email you received if this applies to you.
