    I never thought an "update" would essentially brick my phone. My 3G became a piece of crap after I updated to iOS4. EVERYTHING is slower and the ipod is useless due to skipping and crashing. There's no way I'm buying a new iphone ever again; I'm just waiting for my contract to be up so I can burn this piece of junk.
    I'll never buy a Mac.

    I downloaded the iOS 4.0.1 and found my 3G phone to be significantly slower.

    I have tried the backup/restore technique and the double "hard" reboot and found the phone just a bit faster, but still much slower than before Ver 4.0.1.

    The new feature of storing multiple apps in one folder is awesome, but after reading some info on this thread I decombined all the apps so there are no folders anymore. This did improve the speed even more BUT it is still SLOWER than before Ver 4.0.1. That feature was the biggest draw for me and now I can't use it if I want my phone to move somewhat fast.

    Please post up any other "fixes" that I haven't tried, besides downgrading to ver 3.whatever again. That'll be the last resort.
    3G, iOS 4, iOS4.0.1 slows down my 3G iphone!!

    there's an iPhone app called Memory Sweep (previous known as Scan Lite, which is what it's icon still shows) that could be worth a try ... allows you to see how memory's being used & free it up a bit ...

    does that mean, I wonder, that one or more apps is a cause of the slow-down- using Location Services in some way, since update to iOS4, that it wasn't before ?

    When iOS4 was released I was sucked into "upgrading".

    My 3G slowed right down to the point where I stopped using it for anything other then a phone. On top of this the BT implementation rendered the contact transfer to my in-car kit useless.

    I lived with iOS4 for a few days, then after the frustration of using a useless slow device became to much I rolled back to 3.1.3 using RecBoot. My 3G is now back to the device I knew and loved before iOS4. On reflection I should never have upgraded!

    OK. Here's the thing. I figure the general purpose of the Apple (mainly Mac in my experience as a 20+ year Mac user) forums are to allow us users to help each other out with tips, tricks, advice, and fixes for all the little problems and glitches that happen along the way.

    Most of the time the problems and fixes are not really major, and are usually 'local' to the machine at the time, even if the problem is common and widespread.

    This however is different. This is an problem that affects an entire product range and has left this once proud device staggering about, cursing at pigeons and soiling itself in public.

    Now here's the thing. Apple have people, good people, who no doubt make more money and drive much nicer cars than the likes of you or I. These people are responsible for preventing things like this from happening. And if, things like this do happen, Jobs forbid, they are responsible for putting it right. They designed, developed, tested, produced and sold us the hardware. They designed, developed, tested and produced software. They are the only, the ONLY ones who have the real answers as to what is going on with our phones and how they can be fixed.

    The rest of us are just guessing.



    Come on Apple, do the right thing, it's overdue. And I guess there are more otherwise previously well functioning 3G iPhones out there in circulation than the flaky G4s at the time of the great press conference of 2010....

    What I find most surprising, is that Apple apparently knew all along that this 4.x upgrade would not work well on the 3G phones, but elected to encourage 3G users to take the upgrade anyway.

    I found this article published May 24, 2010 , which was weeks BEFORE the 4.0 upgrade was released to us. Give it a read : http://www.businessinsider.com/apple-probably-killing-the-iphone-3g-2010-5

    It's not just the 3G, as I have several friends that hopped on board when the 3GS was released and they are experiencing the same slowdowns/stutters/pauses.

    Just to add to the discussion, have tried the above fixes, wipe, reset etc. They have not worked.

    It is getting to the point where I am missing calls due to the increased lag of trying to unlock the phone. This is a complete joke, and reminds me of Apples support of the "there is not a problem with our LCD screens even though there has been thousands of complaints."

    I guess I will be contacting O2 tomorrow and requesting a warranty replacement.

    A warranty replacement isn't going to change anything. The only real fix for now is to downgrade to 3.1.3 again. Getting another phone running 4.0.1 is just going to be another phone running 4.0.1, which will have the exact same problem since it is running the exact same problematic software.

    It will, since the warranty replacement should have 3.1.3 on it. I doubt very much O2 will go through their old stock updating all the phones to the latest OS.

    Just put 3.1.3 on the one you have now by yourself. Making companies go through unnecessary expenses isn't very honest.
