    OK, it's just got worse - so slow, slider doesn't respond, and it times out before I can answer a call ! So it's no use as a 'phone, either ...

    I'll put another feedback to Apple ...

    There is another iOS update some time soon

    Apple isolates iPhone 4 reception issues, offers software fix
    http://www.loopinsight.com/2010/07/02/apple-isolates-iphone-4-reception-issues-o ffers-software-fix/

    Tho it maybe aimed right now at the wrong Signal bar strength shown


    “For the vast majority of users who have not been troubled by this issue, this software update will only make your bars more accurate,” said Apple. “For those who have had concerns, we apologize for any anxiety we may have caused.”

    Maybe that explains why our 3Gs sometimes show good signal strength which fades away as soon as we try to use it !

    Same here with the volume...its ******* me off....my car adjust the volume control through acceleration in my car. So when I speed up the radio turns up the volume for road noise. Now I have to turn up the volume when Im parked or at a stop light because its so soft. Come on Steve Jobs you can take away my bars but not my music!!!!

    OK! I finally did it! If you are like me and are still using a PPC Mac running OS 10.5.8 you were saddened by all the fixes that only worked on Intel machines. So here's how I did it.

    *1. Download old OS*
    http://www.iclarified.com/entry/index.php?enid=750
    download the file {3.1.3 (3G): iPhone1,23.1.3_7E18Restore.ipsw} or the file
    {3.1.3 (3GS): iPhone1,23.1.3_7E18Restore.ipsw} depending on your model phone

    *2. Download RecBoot*
    http://www.sebby.net/443-recboot-final-release/

    *3. Read and follow instructions here*
    http://lifehacker.com/5572003/how-to-downgrade-your-iphone-3g%5Bs%5D-from-ios-4- to-ios-313

    Now here's where it gets hincky. I am lucky that I also have an Intel laptop. Yes, +you will need another computer+, your spouses, your friends, one at work.... sorry. It's the only way. It took me two attempts, but I was successful.
    You'll have to transfer all the downloaded things to the Intel machine (or just download them there to begin with). I found it easier to put the files on the desktop, as for some reason, the 3.1.3 OS file always got put into the trash when I plugged the iPhone in.

    Follow all the instructions above in #3, but when you finally get the RecBoot program to dump you out of the re-boot process, you eject the iPhone from the iTunes app, plug it into your old PPC (where all your apps and iTunes library are), and DO NOT RESTORE FROM BACKUP! Set it up as a new phone.
    Yes, you will have to re-install all your music, apps, etc. but you'll be back in OS 3.1.3 and life will be good again.!

    I agree completely.

    What I don't understand is why iOS 4 for iPhone 3G isn't written to swap memory to the flash media (when plenty of free space exists) gist like to good OLD days of virtual RAM.

    Even Microsoft figured out how to do that in Vista--plugging in a flash drive would let you even boost DESKTOP performance by writing frequently used small chunks of data to the flash drive and managing usable RAM in a more fastidious manner.

    May I help?

    I performed a backup, did a factory restore of the OS and then restored my Iphone 3G with the backup. After I did two Hard Resets as suggested below and so far my Iphone 3G seems to be running faster than when I did the initial upgrade from 3.1.3 to 4.0. So far so good...

    Here's why:
    1) speed
    2) power consumption

    Well, after recently having an issue updating my iPhone 3G 8GB to iOS4(**** and back), I managed to get it updated.

    I've been running iOS4 for over an hour now and its running terrific, no slowdowns. Might be placebo but it seems to run more smoothly than 3.1.3, so I'm having none of the issues that other people are with their 8GB 3G's. I can't comment on battery life though, I will in 24 hours.

    Simply giving my input, a census.

    @Chifte,
    Could you try opening a few web pages with Safari, and leave them open. Then use your iPhone for other things and see how it responds over the next day. There is some evidence that the open web pages consume the limited free memory (the RAM) in the 3G, and that this leads to the slowdowns others have been experiencing.

    Thanks.

    Will do D.R.C, I read what you said this morning and I've kept 8 pages open ever since, 6 hours later the only thing I've noticed is a slight lag in text messages when immediately going from one app to msging but 3.1.3 would do that from time to time too, battery wise it's the usual usage.

    I found a fix for slow 3G's with the 4.0 upgrade. Mine was painfully slow. I took the advice of someone else in this thread about restoring the phone. I have MobileMe, so I wasn't worried about losing contacts, etc. I restored the phone, chose "set up new phone" rather than restoring the previous backup (this is halfway through the restore process), then let the phone sync up to MobileMe during it's setup process.

    Now the phone works like it's supposed to. It has extra features that actually work (ability to create folders is one), and no loss of speed. I should also add that I chose to sync far fewer apps this time. Only the ones I really use. I do not think it would matter, however. The phone seems like it's working properly.
