    Fellow Macheads,
    I tried to install the new 4.2 software on my iPhone 3G and iPhone 4, but found myself only getting to about 1/2 to 2/3 on the iPhone's progress bar while on the Mac the progress bar was virtually at the end. I waited for hours, but nothing past this point.... Also, I had a heck of a time getting the iPhone to show that 4.2 was even available - it kept saying 4.1 is the latest software. I unplugged and plugged back in - spent virtually hours and hours on this project.

    Then I put both iPhones in DFU mode - no luck. I had exhausted every effort including checking to make sure I was on iTunes 10.1....

    At the end of the day, do you know what was wrong??? I finally figured it out - I had WiFi Sync installed and it was somehow interfering with the update.

    Here's the uninstall link:

    I also had to do a full restart for this to work properly.

    Take this post with a warning - if you have WiFi Sync installed you MAY have the same exact problem as I have had... I fixed it by uninstalling Wifi Sync!

    Good Luck and Happy Updating!

    I don't know about your issue specifically, but I always put my phone in Airplane mode before updating so a phone call doesn't come in at the exact wrong second.

    Just a guess, but would Airplane mode have helped with your problem too? If so it'd probably be the simplest way to deal with it.

    This is when installing the new iOS - there is no option to use airplane mode.

    He means put it on Airplane Mode before starting the process.

    What would this do?

    This update problem with WiFi Sync effects the Mac and the way iTunes communicates with the iPhone.

    It's the same with Windows, the WiFi Sync server and iTunes 10.1 do not play well together.

    That's been the case for months, there were threads during the summer about this. WiFi Sync, although a great idea, is a bug-ridden piece of crap which the dev should be ashamed of taking good money for and never updating.

    I recall having it in airplane mode actually screwed an upgrade before. I don't put it in airplane mode, comms service is shutdown anyway when the process starts.
