Hello guys this is a tweak that will actually speed up your phones 3g, 4g, and wifi. This tweak actually works it is not like those other mods that claim that they work, but they just end up wasting your time and not working. This tweak actually works I have tried it on cm9 and it works perfectly no problems. If you guys are running a gingerbread rom or sense rom then all you have to do is flash this zip located right here. For the rest of you guys who are running Ice Cream Sandwich roms then what you have to do is also go to the link and download the tweak. Unzip the tweak and get the "sysctl.conf" file from the zip. and put that file on your sd card. Then you have to get a file explorer that allows you to browse as root IE. es file manager. Then you have to go to system/etc and there will be a "sysctl.conf" file already in there so you have to rename that file to "sysctl.conf.bak". Then you paste the file that was on your sd card and put it in the system/etc and then reboot your phone. If you get confused with this then watch my video on how to do it is located below this post. Thats it guys that is all you have to do it should work. This tweak does actually work so give it a try.
