How you do this crap? i follow instructions and My 3G shows the boot logo...Flashes...Now the recovery Logo. i had to restore but i really wanna know how to this mod. So can someone please give me steps.
My FStab For My iphone 3G:
sysctl -w hw.cpufrequency_max=540000000
sysctl -w hw.cpufrequency=540000000
sysctl -w hw.cpufrequency_min=500000000
/dev/disk0s1 / hfs rw 0 1
/dev/disk0s2 /private/var hfs rw 0 2
i use a alternate file transfering way like "diskaid" And "ifunbox"
its the same as Winscp but without passwords and stuff
Im on 4.1....i know its not tested but i wanna test i just need the right instructions

I think u need to remove a '0' from your last (minimum) string. Better yet, instead of 5000000000, make it 050000000.
Right now, you are setup to have your minimum processor speed running at almost full capacity!!!!

Why do people still talk about this. It clearly does not work. Just "under clock" it and see if it reduces performance. It won't, it does nothing.

I'm kinda thinking the same thing! When I first did it, the phone seemed snappier but now that I've used it for a while, it doesn't feel any faster than normal. This is on an ip4, though, but the 3Gs and 3GS' I've done this to still feel quicker. Verdict is still out on this mod.....

I've said it few post back already
The reason 3G, especially 3G feels snappier might be cuz of that fact that in order for this to work you have to reboot and we all know that restart wipes memory clean, and kills all processes. In other words after you restart a 3G it will almost every time feel snappier until you start loading all of other apps and then it will gradually slow down.
Iím sure there is a file where you can alter processor speed but Iím pretty sure this isnít it.

the fstab command is not what controls clock speed. something tells me its just a check, which in theory may still work, but you would also need to tell the phone's CPU to clock at that speed. So while the check is registering a 3G at 600MHz, its still 412, and waiting to be changed to match the check...if i make no sense then lemme know cause i'm not an expert on the topic, but i am knowledgeable..

Ugh Jesus! This whole thread is FICTIONAL! My 3G is USELESS. i tried disabling daemons but i didnt tried the delete language packs. Langauge Packs seems useless to me. its just memory freeing up

Mods, delete this thread already. Hate to see someone come along and actually attempt to do any of this.

Doesn't work anymore, but Didn't it work pre-2.0?

Use the reset function in the general section in the iphone settings and select the reset all settings then you will find that you get a dramatic speed increase. However, you might need to do this every month or so.

The reason why it gives the impression that this fstab mod works is because once after you reboot the phone, you flush the RAM; thus, giving us the added-speed/"snappy" impression people are seeing. This is true of every reboot--not the fstab mod.
After applying this mod to prove it's fallacy, on my iPhone 4 iOS 4.0.2, I ran Geekbench and scored 362--this was a while after toying with some apps. On the second reboot and without launching of any apps, I ran Geekbench, again, it scored a 378.
As far as the iPhone 3GS/4 goes, the baseband runs a check on boot to make sure the kernel doesn't run at a non-intended clock speed.
Save yourselves the trouble and delete this thread before someone ends up restoring their devices.
