    A few days ago I tried out iTunes 10.1 beta. It did not detect my iPhone 3G. Today I installed iTunes 10.1. It also did not detect my iPhone 3G. Here's a picture of what I mean.

    Whenever I connect my iPhone to my computer iTunes freezes for a few minutes. This never happened with iTunes 10.0.

    Here is some other info from the diagnostics test.

    Microsoft Windows XP Home Edition Service Pack 3 (Build 2600)
    Dell Computer Corporation Dimension 4600i
    QuickTime 7.6.8
    FairPlay 1.10.14
    Apple Application Support 1.4
    iPod Updater Library 10.0d2
    CD Driver
    CD Driver DLL
    Apple Mobile Device
    Apple Mobile Device Driver
    Bonjour (214.3)
    Gracenote SDK
    Gracenote MusicID
    Gracenote Submit
    Gracenote DSP

    iTunes 10.0 always detected my iPhone. Anyone know why this version won't detect it?

    experiencing same issue - just updated itunes (10.1) & 10.6.5

    i've just updated my macbook (2006) to 10.6.5 and itunes 10.1 and having the same problem: unable to sync/detect my iphone 3g running 3.1.2

    not keen to update to ios4 - as the 3g runs slow enough already now, but suspect this is the reason - is ios4 a minimum requirement now in 10.1?

    i was about to upgrade iphones too and wanted an up-to-date backup to transfer the data ...
    not great timing! looking to downgrade itunes now...

    It syncs sometimes but not all the time.

    Now iTunes Helper turned itself off.

    Same issue

    My iPhone 3G had problems being detected/syncing starting with iTunes 10.0. I found that the 3rd party USB cable I was using to sync my iPhone with was actually causing the issue. As long as I use an Apple supplied USB cable it is detected and syncs just fine. Hope that helped.

    I was using the USB Cable that came with the iPhone.

    I have a similar problem with iTunes 10.1 - it doesn't recognize my iPhone 4.

    I followed Apple's troubleshooting tips and found that when I re-install 10.1, it starts recognizing the phone again. But when I restart, it doesn't anymore. I can then re-install 10.1 and once again it will recognize the phone.

    Getting these messages in the Console:
    11/17/10 14:13:08 usbmuxd[30] _connect_to_port (thread 0x100687000): Could not connect to USB mux port 32498 for device 7: Connection refused
    11/17/10 14:13:08 usbmuxd[30] _MobileDeviceConnect_locked (thread 0x100687000): Could not connect to lockdown port on device 3cfb691d447458a52ae7d7408c5e72b6fcd5f901.

    I think that's it - don't know what it means though, or how to fix it. Other than re-installing iTunes yet again.

    Edit: Tried uninstalling iTunes completely, including the mobile helper kext - no dice. It works whenever I re-install iTunes, then stops working every time I restart. Annoying.

    After searching the internets wide and far, I figured out that this has to do with the iPhone SDK installed on my system. I re-installed the whole 3GB package- that didn't help.

    But after that, System Update offered me the "iPhone SDK Compatibility Update 1.0" - 6KB. It's for when the SDK screws up your system and the phone isn't recognized anymore. Installed, and problem solved.

    So in my case, this was the iPhone SDKs fault. I don't have the latest version, maybe that has something to do with it too.

    Since the OP has Windows, it's not the same issue. Sorry!
