    Scan Lite has been renamed to Memory Sweep (by Gary Fung). The app has the same icon, so I presume this is the new app name.

    My upgrade worked but experience lethargic processing of changing menus, entering text, and maps. Very frustrating. If Apple doesn't fix this, I will not be interested in the iPhone 4. Come on Apple.. live up to your standards!!

    a double re-boot has sorted the problem for many people, as mentioned by some in this & other threads :

    press power button and home button at the same time, hold until 'phone reboots (ignore the power-off prompt slide bar, keep holding) ... let 'phone start-up normally (Apple logo) ... when all done, do it again, repeat this process ...

    Has there been any news of a fix? I now HATE my iphone.. it is very slow.. many of my apps, that I upgraded to the IO4 update, now crash three or four times before they finally open.. I tried downloading a movie through Itunes store(since its suppose to be a new feature of the OS4 upgrade) and after the movie downloaded I couldn't open my itunes at all, not even to listen to music (and I had a 5 hour drive that morning). I travel 4 times a month and do not take my laptop (thus the reason I bought the iphone) and everything was great..UNTIL the OS4 upgrade.
    Please Apple..FIX THIS ****!!!!!!!!!

    I too had unusable Iphone 3G after a 5 hour update. I did try the double reset a few times but it always reverted back to sluggish performance after an hour or two.
    I have seen tips in this topic, to restore from a backup. I was a bit reluctant to do so but....
    I did just that. I made a backup from my updated phone. I did not attempt to get back to V3. Then I did a restore from backup. Took about 10-15 minutes I think, not long.
    Result was the original speedy performance that I got before the upgrade. It is been like this now for 3 days with no sign of slowing down.
    It is worth a try if you haven't already.

    @volklpaige,
    Apple doesn't read these forums. Please direct your feedback directly to Apple so that they will be aware of the depth and breadth of the many problems affecting the 3G. Simply cut and paste the text that you posted here, and submit it to them.

    Following double reboot and no change. I spoke with staff at ATT no solutions and spoke with apple who said like many on here restore.....I did this through itunes and set up as new phone I was all backed up first and use mobileme. I have reset everything now and it does seem much better generally faster than it was text is still slower to open but considerably faster that before restore. Just make sure that when you back it up copy the back up to somewhere else before you reconnect the phone and disable automatic sync. It seems to have overridden my previous backup.

    lets see how it goes over the next few days.............

    When you reload/resync your music, videos, playlists, did you loose anything? Were all you pictures and applications and music still there? Is there anything I need to be specifically aware of? Thanks.

    When I restored from a backup I had made right before the restore, I lost absolutely nothing, .apps were in the folders I had just made, apps OK, music Ok, SMS message history Ok and so on..., just as you would expect.
    I was a bit nervous as well.
    If you have a choice of backups then I think Itunes chooses the most recent by default but just to make sure just before I did the backup I changed the name of the phone in the device list to something that I would recognise, something like "myIOS4" then when you are offered to choose the backup, you will know exactly the one to select.

    I had the same issues as the other persons in this thread. My 3G became painfully sloe after upgrading. Rebooting made it a tiny little bit better, BUT only for a very short amount of time. Afterwards it became as slow as before. Worst is the loss of responsiveness when typing mails or surfing in the web.

    Downgrading solved the problem for me for now. It was rather easy. I just downloaded the 3.1.3 recovery file (approx. 200MB), clicked in iTunes 9.2 with Alt on the recovery button and waited some minutes. Afterwards there was an error 1050 (I think). I needed to run the program RecBoot to finish the process. Afterwards I got a clean 3.1.3 3G phone, that just had to be filled with content.

    On the other hand I plea to Apple to bring an upgraded OS that can be run on the 3G! You shouldn't be forced to use an old browser when surfing the web!

    Thanks to all whom made suggestions, I used a combined approach. My 3G with iOS4 is now "snappy". I was having problems across multiple applications, screen not responding, etc. FWIW, here's what worked for me:

    -Deleted Safari history, cache and cookies
    -Cleared recent search history in Google Apps
    -Cleared recent search history in Maps
    -Cleared all text message threads
    *These 4 were giving me fits

    1) ->Settings->Reset->Reset All Settings (I did NOT select the one to erase all content)
    2) Allow reboot to home screen (or power off, power on, can't remember)
    3) Upon fresh boot, do the hard reset (hold power/home buttons, ignore slide to power off, keep holding till black screen)
    4) Power up
    5) Repeat hard reset (step 2)
    6) Go back in an tweak all your settings back the way you like (I assume if you were changing them, you'll know what you wanted..iOS4 had a bunch of new stuff anyway)

    I did all this in about 15 minutes. Everything is as fast or faster than with 3.x of the OS. Text message new window is only thing I noticed that might be a shade slow...but its "fixed" compared to what it was after initial upgrade to iOS4...it no longer hangs when sending new text in a thread (which was driving me NUTS!)

    Thank you, thank you, thank you to everyone. I work from my iphone, 6 hours of calls a day and could not afford to be down for a restore or attempt hacking back to 3.x
