If you are interested in buying the HTC One X for its Snapdragon S4 CPU clocked at 1.5GHz processor, I should say that there are cases when there is no need to hurry to talk about the Snapdragon S4 CPU clocked at 1.5GHz processor.
The HTC One X, which was launched via AT&T and Rogers, or as you know the HTC EVO 4G LTE runs the above mentioned processor, while the international version is based on a NVIDIA Tegra 3 processor and this is because of LTE support. But you will find many geeks that are not sitting tight. On XDA forum one of them has posted that he had overlocked his device up to 1.8GHz. As you see this is 20% more than the original phone can.
The instructions will work on any Qualcomm MSM8960-based rooted HTC One X. Do you have such a smartphone? If yes, then you can use this method for browsing the net a few seconds faster, why not?
Before doing this, you should know that if you add this trick to your device you will lose the warranty.
