A video comparison by Adrian Nier shows that the iPhone 3G performs significantly slower on iOS 4.0.

Camera Launch: 40% slower
Camera Shoot: 54% slower

Settings Launch: 125% slower

Safari Loads NYT: 37% faster

Also please note that if you decide to jailbreak and enable multitasking this will make your iOS 4 device even slower!

Take a look at a comparison video by T. Payton below...

Any one notice tethering option showing a working pinwheel. I believe that is slowing my 3G iPhone drastically.

My camera opens faster and takes photo's faster than both these iphones in this video, settings takes a little longer than the 3 version, but faster than the iOS4, and safari .... well you cant really test that as the internet is not precise enough to do a comparison, at the moment I didnt notace a significant decrease in speed ...

I don't see this issue on my 3G. Mine load in same time as 3.1.3 shown in video. Didn't have any issue with jailbreak and unlocking. Works great on T-mobile.

i have a 3G and its always been hella slow. iOS4 did not affect performance and im running it on a jailbroken 3G.

I have iOS 4 on my 3G and this video sums it up!

detective sims - June 22, 2010 at 10:18pm

My 3G is NOT jailbroken!

If you jailbreak/upgrade a 3G iPhone to iOS4 with redsn0w, you will see the same sluggishness as the in the video. I say this from experience. But if you start over again and use Pwnage Tool 4.0, your jailbroken 3G will be even faster than when it was running 3.1.3. I don't know why this is the case, but it is a night/day difference. Redsn0w is the culprit, not iOS4.

yes you are absolutely right. I used the pwnage tool to jailbreak now and my 3G is faster with iOS4 than 3.1.3

I thought multitasking does not work on the iPhone 3G. If not how do you enable it?

detective sims - June 22, 2010 at 10:11pm

It doesn't (with the initial software update), you first have to go in to the restore 4.0 file and set multitasking to "True". See this: https://www.iclarified.com/entry/index.php?enid=8777

I'm sorry, the capabilities plist.

This test and post is rubbish. The fact is that if you have multitasking enabled your setting, camera and everything opens up in a flash - as long you dont have too many things on memory. Just simply because multitasking puts these on the memory so when you open them again they really open fast - faster than ever! You only need to remember to keep eye on amount of the stuff you have on the multitasking list - killing the big ones you dont need to open again soon... My 3G is flying in basic usage - vs. 3.1.2 and below...

A poll over at macrumors keeping track of such claims.

mike - June 22, 2010 at 5:31pm

they need to overclock the 3g on my g1 i overclocked to 657MHz when it was originally 528

Anthony - June 22, 2010 at 5:23pm

I have a 3Gs and my 3G does not even work on my phone right now... its frustrating me

Lucia - June 23, 2010 at 10:10am

My 3G isn't working either. What did you find out on it? I was told that there is an issue with some phones with the update. Apparently Apple have been notified. At first I thought my phone was screwed in some way.

Donald G. - June 22, 2010 at 5:22pm

I have a 3G on iOS 4 with multitasking and it's way faster than before.

asd - June 22, 2010 at 5:18pm

mine is wayyy faster than the 3g on ios4 in the video there is something wrong with his 3g

Colojomo - June 22, 2010 at 5:17pm

i sure hope this is not true, people please post your results, even if opinions only, because i dont think WE want it running any slower than it is now, 2.X.X to 3.0 was a major slowdown IMO

Ramses - June 22, 2010 at 5:11pm

good i did not upgrade. 2.2.1 was fastest i think ...

Ciaran - June 22, 2010 at 5:02pm

I'm using an iPhone 3g iOS 4.0 and I got slower than the video (although I do have multitasking enabled)

Chris - June 22, 2010 at 4:53pm

I believe the iPhone 3G with iOS 4.0 used in this demo probably had to many stuff installed or had problems because I tested my 3G with iOS 4.0 in conjuction with the video and the loading speed was the same or maybe faster than the 3.1.x used in the demo.
