ITunes 9.2.1 & iPhone 3GS 4.0.1 - can't update software

Question

I currently have iTunes 9.2.1 and when I try to update it it says: "This version of iTunes (9.2.1) is the current version"
When I try to update my iPhone 3GS through iTunes from 4.0.1 it gives the exact same message. "This version of iTunes (9.2.1) is the current version"
Please advise.
Thanks

The EXACT same thing is happening to me. My phone is brand new, so the fact that I can't activate it due to this problem is really frustrating. I've uninstalled and reinstalled iTunes several times, followed apple's instructions in its problem solvers guide...nothing seems to work. I've messed around with the drivers a bit too, with no luck. Anyone have any ideas?
Go to the Event Viewer (Control Panel || Administrative Tools || Event Viewer) and look under Windows Logs || Application. Do you see any Bonjour errors? Since Windows 7 recognizes the camera part of the iPhone (nicely done Win7 integration!) Microsoft is probably not the culprit here.
Uninstall/reinstall iTunes is part of the process, but you also have to make sure you uninstall all the other components Apple installs (Apple Mobile Device Support, Bonjour for Windows, QuickTime), do a reboot, and then install everything from scratch. That may fix the problem.
This is exactly what an Apple guy talked me through over the phone. (I think I even uninstalled Apple Software Updater) I had a similar problem with the iPad on Win7 x64 - it was Bonjour that is the culprit. The x64 flavor of Bonjour for Windows is not as stable as the 32-bit version.
But everything has been golden for me since the reinstall...
Give that a try.
Then if not, you could start looking to see if there is another ZeroConf/SSDP provider that is conflicting with Apple's somehow.
