Tempted by a Galaxy Tab this morning? T-Mobile USA has thrown open sales for the 7-inch Android tablet, with the price of entry being $399.99 with a new, two-year agreement or $599.99 contract-free.

As for the data plan, T-Mobile has two options. $24.99 per month gets you 200MB, while $39.99 gets you 5GB; both come with unlimited use at T-Mobile WiFi hotspots. No voice plans, of course, since the North American versions of the Samsung slate won’t make phone calls, but you do get unlimited SMS and MMS with both data plans.
