    Well like a lot of you I updated my 3G. What a mistake that was. Took hours and hours. End up restoring it. I had to delete the .ipsw file. By doing that I was able to restore. I am running iOS 4 but cannot sync. itunes locks up. Cannot get my music from itunes onto my phone. This really sucks.

    I know it's early but is there a fix? How can I go back to 3.1.3?

    Sucks to be you, but yes you can go back to 3.1.3. However you will be stuck on the latest modem fimrware, which is 5.something.13. First you need to find the 3.1.3 .ispw for your model. You will also have to restore it from scratch. You will need to get your phone into DFU mode and if it fails, which is highly likely, you will need to use irecovery to get it up and running.

    It's easier than it sounds.

    Not sure why many users are having a hard time with 4.0. Last night when i did the upgrade to my 3g S 32gb from start to finish including backup and the download for 4.0 was only 17 min... and my iPhone runs really smooth, no problems. I also find that my battery life is MUCH better than 3.1.3.

    I've been wondering this same thing. On my 32Gb 3GS, I went from Jailbroken 3.1.3 to 4.0 GM to 4.0 Release. Everything went smooth and everything seems to be working okay, apps and hardware. What could be different for those that had, or are having problems?

    I did not have any problems except it takes 1 hour for my phone to back up. 3gs 16 gig. Mine is not jailbroken either. It took that long every time I back it up even without the 4.0 roll out.

    Well the basic statistic missing from all these threads is if the person upgraded from a jailbroken device instead of a non-jailbroken device. If you are jailbroken, it is recommended that restore as a new phone before you attempt to install 4.0. I can only wonder how many problems there has been as a result of people not following directions.

    I did go from JB 3.1.3 to 4.0GM to 4.0 Release, but, each time I did use the Restore. The first time to get GM on the device, I used shift+Restore tok find the GM file on my computer. To get to the final release, I clicked restore. I then restored from backup to get all apps and settings back. And, as I stated earlier, I had no problems and all is well.

    So, I think you may be correct about JB's not using the Restore button to get the update.

    That is the exact same procedure I used and I didn't have any problems either.

    Not necessary. I was 3.1.2 jailbroken with blackra1n many months ago and did a simple upgrade and had no problems at all with the upgrade. There was a Google sync issue but that was a coincidence and had nothing to do with the upgrade. Google resumed full service and sync processes in the past hour.

    A big part of people's problem was the very long time for backup of their iPhone. Mine took about 5 hours but I did the backup in the morning BEFORE iOS4 was released. The upgrade itself took about 20 minutes or so.

    I miss some stuff from my jailbreak (true multitasking with backgrounder and proswitcher; SBSettings) but will be without this by Thursday anyway when I pick up my new phone.

    I've tried this several times since yesterday and once I start downloading 4.0, it says it's going to take 2+ hours to just download. Screw that! I'll just stay on the 4.0 GM seed for now. Anything more than 15 minutes to download is useless.

    I have the 3GS 32g and the update was so fast and easy! Less than 10 mins ( I had backed up already per Alli's advice in posts earlier) and it was really easy. I am not JB though. I don't know how that might have affected it

    Mine was fine with the GM candidate and fine with the public release. I wonder why people are having issues.

    The only reason that I'd go back is that my 3G is SLOW...Trying to learn to live with it...until I can get a new iPhone that is!

    it's going to be hard to say why people are having problems there are so many variables and combinations of things that affect the outcome. Is it 3G or 3Gs? is it JB or not? what JB pwnage tool, blackra1n, Spirit,etc. if JB how customized was the phone? Mac or Windows? Which OS 3.1.2,3.1.3? and on and on. All I can say is mine was on iOS 4 in about 10mins that's downloading to complete I was surprised at how fast it was. I have a 3G and I was JB on 3.1.2 using pwnage tool which I always used since 1.x and I just did a sync, did a backup, hit restore and that started the upgrade to iOS 4. After I restored from backup and I was ready to rock and roll.

    Mine aswell. Ive had ios 4 running on my 3G for 24 hours now and damn its so slow and laggy. Like pressing home to unlock the phone and getting a second or two delay, typing in pin and not seeing the dots for 2 or 3 seconds.

    Seriously considering downgrading right now.
