The Samsung Galaxy S 2, the best Android smartphone to date, has sold over 5 million units in less than 3 months. It will be launched in the U. S. next month.

The Samsung Galaxy S II will be shipping with the Nvidia Tegra 2 chipset inside in some regions of the world, instead of Samsung’s homegrown Exynos chipset.

The folks over at Pocket Now have managed to get their specs of the hotly anticipated successor to the Samsung Galaxy S – the Galaxy S 2 – thanks to Expansys.
