IPhone 3GS iOS 4.2 - iTunes Update 10.2 killed Apple Mobile Device USB Driv

Question

I have Windows 7 64-bit professional. This morning I received notice that I needed to update my iTunes software to current version. When I ran the update, the USB connection no longer would recognize the phone.
Multiple attempts to repair, even reinstall iTunes, ALL Apple software per Apple Support articles has failed. I cannot sync my phone to the computer to update the sofware. Even after a clean install with virus software turned off, and manual attempt to update the driver, I still see the yellow exclamation point in the Device Manager for Windows.
There appears to be an issue with the update released last night and Windows 7 64-bit systems. My iPhone and iTunes were working fine until then, sync everything worked good.
Anyone have any suggestions. I understand from a search on the Internet that this is a common problem and that Apple does not have the ability to separately install a current Windows USB Driver that actually works if you have this problems.

Answer 1

Here is what worked for me on a Windows Vista System. I had ssue with both 10.2.1 and later 10.2.2 and have been on this site daily since release of 10.2. Finally I found something that worked for me. I am using iPhone 3G Version  4.2.1 seems Apple stops there for me so hopefully I won't need to update iTunes again.
  Completely uninstall the current version of Itunes including Apple Mobile Device Support, You will find it after going to Computer, Make sure you delete both of them.
Next install the latest version of itunes from the apple website. Make sure to download the correct one as there is both the 32 bit and 64 available.
Now the problem with AMDS might still persisit as it did for me. So you want to uninstall Apple Mobile Device Support (again), you will find that after going to computer and uninstall programs. Note: At this point I found 10.2.2 at least gave me impression AMDS was at least now running however iTunes crawled when opening, froze for minutes when I connected iPhone and failed to see any device connected when it was again running. So do not stop as I did the problem may still be AMDS and only AMDS.
Next install itunes 10.0.1  http://www.oldapps.com/itunes.php , Just scroll down until you see 10.0.1
Save it to your desktop or somewhere visible.
Next install UniExtract
    http://www.legroom.net/software/uniextract
After the installation is complete go to where you save your itunes file, right click and click on uniextract
files.
Press Ok and make sure its set to your desktop.
    On the next screen when prompted to choose an extract method, choose "Not an Installshield
    installer".
Next open the folder you extracted and go to Apple Mobile Device Support and install it. Once complete
    Restart your computer and it should work.
Good Luck! It only took me 21 days to find something here that worked. Now I am hoping it can help someone else.  If not, well there is always tomorrow and someone may find another solution it seems 10.2 is not the best for all.
