    OS 4.1 also makes a BIG difference on my iPhone 3GS, it looks like they finally worked out the sluggish performance across the board.

    just updated to 4.1 on my 3G. TONS better than 4.0.2! Can’t say if it is better than 3.1.3 was. It’s been a while since I’ve run that. I re-checked my Spotlight Search options and still seems to be working faster than 4.0.2. Maybe now I won’t have to use Dragon Search to find info online faster than my phone could find info stored in memory…

    updated my iphone 3G to 4.0, then 4.0.2 and now 4.1. For 4.1 did the restore as recommended for best results. Now marginally better performance, but still much slower than before any updates. Calendar in List View comes up then goes completely blank and only comes back if I change calendar view to Day or Month and then go back to List. Still have delays launching apps and text message app. All Spotlight searches turned off. Very few apps on the phone. Only 10% of memory used. Very frustrating…

    I updated my iPhone 3 to 4.1 but now I cant send picture messages. The camera icon has gone in the message app and when you go into the photo’s folder there isn’t an option to send a photo either. Anyone else having this problem?

    I will never forgive Apple for not warning all the 3G customers about this performance debacle. No 3G should ever have been upgraded without a very public disclosure of the consequences.

    This is what happens when one company gets so much market power — in this case, over the mobile market — and when the switching barriers are so high to go elsewhere.

    We have six iPhone’s in our household, but will be switching *everyone* over to google devices when our pathetic AT&T service contract expires.

    Well if your jailbroken on the iphone 3G you can have multitasking and wallpapers only if your willin to openssh some files. For exmaple on testing I found multitasking runs perfectly on iphone 3G with out background. But once added with the wallpaper background, the sluggish performance appears and you loose the speed. MY suggestion is once openssh delete anything begginning with Wallpaper in /System/Library/CoreServices/SpringBoard.app and it will fix all problems but ultimatly give you multitasking and wallpaper. Although you will loose that nice shadow effect but its a good trade off for performance but still have all the features

    The 3G is very slow with IOS 4.x. I think you should better keep it with 3.1.x versions. I had 2 3G to update to 4.0, but both of them were slow, so by using SHSH blobs I went back to the previous versions. I think similar with the 3GS thing though, it’s also not performing very good under 4.1 currently, I may think of going back to 3.1.3. Only the iphone 4 is performing exceptionally under IOS 4.1, but I hate the multitasking of the Apple, I think I will close it as soon as “Proswitcher” becomes available in 4.1

      Other than disabling Spotlight, your best bet is to wait for the iOS 4.2 update which is said to further improve iPhone 3G performance.

      On a related note, iOS 4.2 is expected to be the last software update for iPhone 3G, so hopefully it will perform well.

    i can honestly say that iOS 3.1.3 is way faster and more stable then iOS 4.1 …I have a 3GS and I’ve ran all the new firmwares and I always jailbreak, I can’t stand the limitations and lack of customization options in the stock firmware… anyway other then folders and the sad excuse for multi-tasking in iOS 4+ that only bogs down my phone and lags it to hell don’t waste your time if u haven’t upgraded your firmware don’t and if u jailbreak your device be sure to save your SHSH blobs with tiny umbrella as apple doesn’t sign off on older firmware versions and makes it so you are unable to downgrade which u will want to do after a couple of days running the newer iOS :P
