We already reported that the Samsung Galaxy Tab was coming to Sprint on November 14, priced at $399 with a 2 year contract and $599 without a contract.

Now, TMONews has leaked a few internal slides by T-Mobile which state that the pricing will be almost similar to Sprint’s.

The T-Mobile Galaxy Tab will be effectively priced at $399 with a 2 year contract and $649 without one, after a $50 mail in rebate. We don’t know the exact launch date, but it will probably be around November 14.
