Doesn't seem like it's working. downclocked my iphone 4 to 400mhz, no slowndown at all.

I just tried this with my 3gs and now im stuck with a itunes screen. . Does this mod clash with supercharged?

I'm kind scared to try this on my iphone 4 becuase its working fine and i dont want to restore it really... i think this fstab file is some sort os script thats run on login thats why it needs the su and then password.

Just thought I'd clear this up; this does not work. It is simply changing a string value, similar to the power management.plist file we have all seen. It does t do anything as we do not have access to modify the kernel.
Don't bother with the chance of bridling you phone only to have it do nothing.

By the way, setting the 3G's values to the 2g touch's 525mHz should provide a good enough speed boost.

I think this is just more a check parameter. You CAN change this, but if it doesn't match the speed it's checked against elsewhere, nothing is going to change.

thanks for this. I notice faster response on my 3g

If it were possible, modifying the speeds from stock to a SLOWER speed should result in decreased performance. In my case, my iPhone 4 experienced no drop in performance whatsoever. I tested this in CoD zombies and load times were identical, frame rate seemed identical, syncing and network access identical. The app even responded identically.
If you can show me some deeper coding than just a simple variable change I would greatly appreciate it, as this topic peaks my interest and would be very much open to further development of a GUI for oc'ing (similar to droids).

Just tried this on my iPhone 4. My values are 900/900/50. Im jailbroken on 4.0.1 with jailbreakme (of coarse). The only speed increase that seems to appear is that Cydia seems to load a lot faster... Everything else doesn't seems any different. Any other iPhone 4 stories?

Does anyone know if putting the values to 1000/1000/50 would be bad for iPhone 4?

I set mine at those values when I first did this tweak. My ip4 worked fine.
Since then, I reduced it to 950/950/50 but I don't have a legitimate reason for doing that!!!

Can this be done on 3Gs 4.1 jailbroken ?
