And, iOS has a Debian Kernel which is based off of unix.

Su is a file you got me, but there's plenty of other files in there that are also named after unix commands. It where they are stored hence the name bin or binary.

You have to mount partitions before you run the commands. For example, sysctl and su are in /bin/ which is on the root partition, which when putting it before the mount it won't work, I also pointed out hw.cpufrequnecy isn't even coupled with hardware, its in iboot,
Oh and it's Darwin btw.

A few things...
I had the root password right for the 3GS. 100% certain, I still have that fstab file locally.
The kernel in use on 4.0.x is Darwin 10.3.1.
This doesn't work. Evidence:
The lower-right terminal window is the 3G I edited fstab on. No change reported from hardware.
Shoot, I was hopeful. At this point, a fiver says that the so-called upgrade for the 3G will blow as much balls as the current 4.0 (and will also plug up the current ultrasn0w unlock to boot).
PS: Anybody have a clue as to why the iPhone 4 in the top-left window is reporting clock speeds of 0 Hz? It was obviously running at the time...
EDIT: Edited fstab 3GS and stock (but of course JB'd) iPad. Both S5L8930 devices report 0 Hz clock speeds... shenanigans?

by default its the normal admin account
on topic, maybe this is too good to be true
it was a funny coincidence my phone stopped lagging after i changed my fstab file
i edited the file on an old phone to max out at 50 mhz, only to see it boot up just fine and nothing change
one is a 3G on 4.0, one is on 4.0.1
it definitely was not a placebo, it was the first time my phone responded fluidly in weeks

Is it safe to assume this works with the 2g also?

What should the Iphone 4's frequency be? 1Ghz?

This does work. color me surprised. I am running jailbroken IOS 4.0.1, and the best test of this overclocking I have done is Tap Tap Revenge 2. Before, the screen would stall every so often when the little orbs were traveling down the screen to where I had to tap them (guitar hero style) and when it would stall, it would become inaccurate in terms of registering my finger hits, or disregard them all together. Then I did this overclock, and it runs butter smooth. No placebo affect here...

Any difference putting the code after the mount points?
08-31-2010, 10:22 AM #54
This hack ROCKS!!! I just did this on my ip4 using 800/800/050 and it's acting like it's on crank! The responsiveness is amazing; even my Home responds faster! Praises to you!

Just did a test. I ran geekbench after a reboot on my unmodified 3GS. The total score was 275. Ran it again after doing this overclocking mod and rebooting on the same phone and the total score was 284. I went 700/700/420
EDIT: nevermind I just un did the mod and ran the benchmark again. Hit 285

I see no noticeable difference on my 3G running 4.0.1 with multitasking and Backgrounds on. Keyboard still lags. Folders still lag. Boot time *may have been 5 seconds faster. Start up times for text, mail, and calendar were exactly the same (just used a stopwatch). I don't think this works for the 3G. Those with the higher end iphones may see a difference, but I didn't. Thanks for the opportunity to try it though!

how do I save the new file as a plist file on a mac? when I ssh it back to the iphone its no longer a plist file.Don't forget to say THANKS!

I don’t want to bash on the OP efforts and I am not too familiar with all this but there is a question that just keeps popping at me:
Q. How come there is no script line with in this file that tell/shows what the stock boot CPU speed is set to?
I mean, if you can change the phone to boot with higher frequency with this method then what is telling it to boot in the stock frequency to begin with… just a thought…
EDIT* - so in esence this over-writes the original command somewhere with in the iPhone??? :/
It is because of this that I don’t really believe that this works…
I support all efforts and mods so please don’t take this the wrong way.

Interesting posts.. Im still using iphone 3G 16g 3.0 JB on pwnage. Luckily, i was able to improve performance by deleting all daemons that were considered safe to delete. Still a slight lag but battery has improved significantly . Very interested in trying this out though.. I just dont want to have to restore. To be honest ive never had to restore unless it was to do a fresh install. I wont lose anything right? Is it safe just to try? I just dont want anything to happen thats all.. Thx.
