Therefore, I don’t have any issue to use Android applications that require root access. Here are my top reasons why you should to root Samsung Galaxy S2.
Samsung Galaxy S II is already a very fast smartphone @ 1.2 GHz. And it can be even better and faster by overclock it to 1.4 GHz or 1.6 GHz. That’s 17% and 33% speed increased.

Windows Mobile 6.5 is not the only operating system for HTC HD2. We can run Android on HTC HD2 (almost perfect) too. Not to mention Ubuntu, Windows 95/98 (not perfect yet). HTC HD2 is a legend powerful mobile phone. Here are the top 10 tips, tweaks and hacks for Android HTC HD2.
Overclocking is not a stranger to me. I overclocked my old Intel Core2 Extreme quad-core processor QX9650 to 3.6 GHz. And I can overclock my HTC HD2 with SetCPU’s help too. SetCPU is CPU speed tweaking application for Android. In details, it allows control of certain aspects of the Linux cpufreq driver by allowing for overclocking, underclocking and tweaking speeds. It works on most rooted Android 1.5, 1.6, 2.0, 2.1, 2.2 builds.
