T-Mobile's been saying it would launch a white Galaxy S II in time for the holidays, and now it's letting us know that the phone will be available exclusively online on December 14th. Pricing is the same as the black model: $229.99, after a $50 mail-in rebate and two-year contract agreement. There are now two white Galaxy S IIs in the US — the other is the recently-launched Skyrocket on AT&T's LTE network. Samsung's also officially launched white versions of the Galaxy S II LTE and Galaxy S II HD LTE over in Korea, a little over two months after first announcing the devices and just over month after they went on sale. There's still no word from Samsung on whether it will bring the 720p Galaxy S II HD over to the States, but we certainly wouldn't say no to another high-res LTE phone.
