This review is of an LG Optimus 2X unit supplied with pre-release software. In accordance with TechRadar's Reviews Guarantee , we have not included a final score for this review. This is our in-depth experience with the version of the phone supplied to us, tested as thoroughly as usual. We knew it as the LG Star originally, and we waited impatiently for a chance to really put it through its paces. Now, the world's first Tegra 2 smartphone, the LG Optimus 2X, has arrived for our delectation, sporting Android 2.2. Mobile World Congress has brought us news of more dual-core smartphones to come, including the Samsung Galaxy S2 , but it's not the same as having one in your pocket. So what's a dual-core processor good for?
