Since I belive the a4 proccesor i's underclocked to around 800mhz could it be possible in the jailbreak to clock it to atleast 1ghz? Just a tought. Any ideas?
 
Once JB if the right utility is built its possible.
But I dont see the reason behind it.
Its fast as it is and to cause overheating, hurt battery life and many other side effects from overclocking a cellphone is pointless IMO.
 
this has been covered a million times on every iphone version. there is no way to overclock the iphone processor. it is hard written (or whatever its called) into the firmware. a simple google search will bring up a few results where there was even a group of people that were donating to this guy that had a lead on it, but eventually said that it could not be done and gave up.

new processor, new set of rules. I hardly doubt that it's impossible - but then again I haven't done a "simple google search" because I don't really care.

To the point listed above - the phone is blazing fast as it is. Why would you risk over clocking it? Just out of curiosity, what are you looking to do w/ an overclocked iphone4 :)
 
Planetbeing thinks the clock speed of the A4 in the iPhone is dynamically scaled. If so, it is entirely possible that it already runs at 1GHz when necessary.

Idk i dint say i wanted the feature I just wondered if it was possible it's just a question.
 
Overclocking the A4 would be interesting. Just to see how much you could get out of the little chip.
 
I think pretty much every ARM (The A4 is an ARM chip just like any other, but Apple made it, nothing special, nothing amazing - just a different brand) chip in every iDevice has been underclocked, and no overclock has ever happened. So I'm going to say there will be no OC for the iP4.

Yea but we never had a4 chips so I think it might be possible
 
The iPhone 4 can get pretty hot. Why would you overclock and risk the additional heat or frying it in the process?
 
The processor is not underclocked, it is clocked properly for best balance of power consumption, heat and speed.

Not if it's liquid cooled - I can see it now :)

Nonetheless, people don't understand that. It's fast enough and it doesn't catch on fire - In my opinion that's a win... but nerds are nerds and will do as they please.

Would be interesting to see

What you're looking for is that the CPU multiplier and the FSB is locked.

Umm just a test to see the real power of the phone it was just a tought
 
wow

to everyone one of you replying to the original question of can the iphone 4 be overclocked..the answer is yes it can and every iphone/ipod touch/and ipad platform has been successfully overclocked.

To the morons who think the iphone is underclocked to keep it from overheating...how hot do you think the cpu gets... its not a quad core i7 that needs liquid cooling ands runs a 5 GHz. every cpu in the qorld is underclocked to preserve its lifespan and in mobile platforms to lessen battery consumption. The A4 CPU does not get nearly hot enough to cause any damage to the phone or itself.

To those of you who dont understand why you would overclock...Do you even know what GHz means? The amount of cycles per second the CPU goes through. So if you overclock your iphone 4 from 800MHz to 1 GHz this means you are allowing your phone to process 200 million more cycles per second so why dont you guys do a little research before posting such ignorant replies.

As for the original question. Yes you can overclock your iPhone 4 after a jailbreak adding the cydia.hackulo.us repo and installing iOverclock. You may also SSH into your iphone, assuming you have OpenSSH installed to your phone, Using WinSCP through a wireless network find your IP for your phone. The username will be "root" and the password will be "alpine". Once in i forget where to navigate to but you only need to change a system power profile filenmae and reboot the device and it will clock to 1 GHZ. I've already done it before you skeptics say otherwise and it does make a difference in multitasking and boot time.
