    Yep - after a day with 4.0.1, it's got worse - ie: going from 3.1.3 to iOS4 ruined it, updating to 4.0.1 at first seemed to partially recover it, but a day further on seems to have made it worse than ever ...

    'still don't understand why everyone isn't tearing their out, why the press hasn't mentioned it, and why Apple has been totally silent ...

    as I recall, there was a similar silence when some people had problem with their Time Capsule, but the problem did seem eventually to go away (thanks to updates, presumably) - 'though we've never dared to try reconnecting ours (the effort required to sort things out if there was still a problem being so enormous)

    Yes, they are deluding themselves, *there is no speed increase for 3G iPhones with iOS 4.0.1.* I decided to update both of my 3G iPhones, and they both run just as slow and with apps crashing just as much as with 4.0. No difference.

    Thanks, Chris, but I don't think that was the case with my phone. I can't tell now, because when I tried to load 4.01, it once again crashed and required a "restore" - but this time it lost everything! I've been unable to get any of my previous settings, email, contacts, calendar, home page items other than procured through iTunes, etc. I still hope there's a way to recover things, but my backup disk doesn't seem to include the iphone backup files - and I can't figure out how to access the ones I do have from a few weeks ago. I'm backing everything up double before trying to access it, because it seems like the iPhone "goes vanilla" and doesn't recognize any previous data every time I try to sync. The implication is that the old data files are deleted, so I'll have to reinstall form the backups - if I can find out how!! FRUSTRATED!! Tom in Kona.

    backups - we found our copy of 3.1.3 in the Trash, where it had been put automatically when we'd allowed Apple to update our 3G to iOS4 ... we pulled it back into the iTunes folder, 'though we've not tried it yet & are not sure what would be in it (just the OS, or our data as well) ...

    I posted this in a fresh thread, but have not heard back from anyone, so I don't know if it is working for anyone else, but it has worked perfectly for me. My 3G is back to normal, and working quickly. Here is my post:

    Like many of you, I have experienced a noticeable slow down on my 3G after upgrading to OS 4.0. After looking everywhere, and trying many of the "fixes" with minimal improvement, I may have stumbled onto a simple improvement.

    I think the new "folders" option, may actually be at least part of the problem. I removed all of my apps from the new folders that I had created when I upgraded, and then I did a "hard reset" (holding down the top button and the front button for several seconds and continuing to hold them down while disregarding the "power off slide" prompt, and not releasing the buttons until the apple icon shows up on the black screen). After a minute or so, the phone relaunched, and -- it is a lot faster!

    I believe that it is as fast as it was before the upgrade, however, I really don't remember how fast it was before, but I KNOW that it is faster than it was before I deleted the new "folders".

    Give it a try and let me know if this helps you,

    @Christopher,
    The file you found in the Trash ( iPhone1,23.1.3_7E18Restore.ipsw or similar) is the v3.1.3 firmware "image" file. It does not contain the backups of your data that were made by iTunes back when you had 3.1.3 on your iPhone.

    Unfortunately, the old v3 backups were also deleted by the iOSlow installer when it did the crapdate† to v4. Wouldn't want to confuse things by having old backups muddled up with the new ones, would we...?!

    I found my v3 backups on my Time Machine volume, located in ~/Library/Application Support/MobileSync/Backup

    Your old iPhone backups may be there too (assuming you have a Time Machine or other backup regimen in place).

    Same problem. It's slow to open some applications and just locks up for 5 seconds or so for no apparent reason. Texting has locked up on me several times, I've experienced problems with mail (not scrolling and just quitting) messages appearing saying (No Subject) (No Content) that you can't delete. My photo album has black pictures in there and today it stopped taking pictures altogether (even tough I still have a spare 1GB). Prior to this iPhone OS3 worked like a dream.

    It's really not usable at the moment. I wish I could revert back to iPhone OS 3 until Apple get around to fixing the bugs because Folders, universal Inbox (in a really slow buggy version of Mail), picture zoom and a new calculator icon isn't really worth having on balance with the slowness and bugs of an upgraded phone.

    I'd like to get an iPhone 4 but I can't sell my 3G as it is and I'm not really very impressed with iOS4 yet.

    Before I got my new iPhone 4, I had the iPhone 3G and have to say, I experienced these same performance "lags". In iBooks, as you said, the page-turns were delayed and switching between home screens dragged along. Sadly, a software update can't & won't fix this. The iPhone 3G's slower hardware just performs slower with iOS 4, a software update might be able to improve speed somewhat but nothing significant.

    It is utter madness to deny the reports of speed increase with 4.0.1. It definitely works for at least some users for at least some time. I still have a very noticeable speed increase after several days with the new OS.

    If it does not work for you, there are certain factors that slow your phone down that do not apply for other people.

    Devices are different. Installations are different. Solutions are different, and 4.0.1 may be the solution for some but not all problems.

    If your only goal is to stubbornly bash Apple for this, feel free to do so. If your goal instead is to be constructive, bash Apple for something else (there are plenty of reasons) and try to solve the remaining problem with your phone.

    Ours, on 4.0.1 now, is a mixed bag - soon after update from iOS4 it seemed much better ('though still regretted updating from 3.1.3) .. last evening it was terrible, this morning it's better again. One or two reasons for this - last evening we were (it's now clear) using a number of apps for the first time since update (camera, a couple of calculators, and some dictionaries), and we had Airplane Mode off in a v.marginal signal area (bars fading to No Service & back again, on a ten-minutes cycle, sort-of) ... this morning, in the same room / area, we've Airplane Mode On & those same apps are faster ... and when we put airplane Mode Off again, responsiveness declines ... seems to suggest memory & memory management issues (?), but who knows ! 'ours are 8Gb 'phones, 'wonder if 16Gb are noticeably better ??

    During the dreaded days of pre-4.0.1, I played a lot with airplane mode, but saw no speed difference in my 8G phone. Could it be the location services? But I doubt you have calculators or dictionaries with location services.

    Yep (they don't, of course) that's another factor ... one of the reasons we're all confused & foundering on this, is it's near-impossible to look at the issues scientifically - nearly no data !

    That we should be in this situation - hardly-usable apps, unreliable 'phone calls, etc - is daft, iOS4 features are nice to haves on a 3G, and none of us would have been upset if it hadn't been offered ... but it was, and if Apple were offering it we were sure it would be OK ... but it wasn't, and the iPhone has gone from being a real help to a real nuisance ... why on Earth didn't they just come clean & immediately offer a simple downgrade option & be done with it ?

    I feel like my phone gets worse and worse every day. An application today was telling me I was having memory errors. I wonder if Apple will give me any remedy with my AppleCare contract. They need to fix this.

    just spoke to someone from apple and he sort of said iOS4.0.1 should fix the slowdown issues currently affecting my 3g iphone (unjailbroken)
    he then said if i was still experiencing problems would i make a record of them and get back to him
