Overclock iPhone 3G, 3GS, and 4!
How to Overclock iPhone 3G, 3GS, and 4!
Hey guys, as far as i know, this works on iOS 4.0 - iOS 4.0.2. So, here are the instructions!
1: SSH into your iPhone and goto /private/etc and backup the "fstab" file.
2: Open up fstab in TextEdit (Mac) or Notepad.
3: Add the following lines:
su
alpine (Unless you changed it to something else.)
sysctl -w hw.cpufrequency_max=???000000 (Replace ??? with the MHz Ex: 600)
sysctl -w hw.cpufrequency=???000000 (Same as above)
sysctl -w hw.cpufrequency_min=???000000 (Replace ??? with the MHz you want when the iPhone is sleeping, etc..)
Add those before:
/dev/disk0s1 / hfs rw 0 1
/dev/disk0s2 /private/var hfs rw 0 2
So, in the end, it'll look like this:
su
alpine (Unless you changed it to something else.)
sysctl -w hw.cpufrequency_max=???000000
sysctl -w hw.cpufrequency=???000000
sysctl -w hw.cpufrequency_min=???000000
/dev/disk0s1 / hfs rw 0 1
/dev/disk0s2 /private/var hfs rw 0 2
4: Reboot your iPhone!
