Joining both Verizon and T-Mobile, AT&T is now rumored to be set to launch the Galaxy Tab on their network November 21st. In a leaked training document it's not only revealed that the potential launch date is the 21st, but also gives us a price: $649.99 without contract.
Now this pricing is $50 more than Verizon and T-Mobile are offering for the device off contract, which is very strange. So far there has been no word regarding subsidized offerings of the Tab.
Data pricing for the Tab will be identical to what AT&T offers to it's iPad customers. 250MB of data will be $14.99 while 2GB of data will be $25 monthly.
