I have a 'new' Dell computer running Windows 7.

Have synced my iPhone 4 to the computer numerous times.

Was prompted today to install the new upgrade to iTunes 10.1.

After installing that upgrade, I am no longer able to access my iPhone from iTunes. I get the message "device driver software was not successfully installed."

I have followed all of the help on the web site, and nothing helps. iTunes cannot access my wife's iPhone 3GS either.

Thanks for your help.
Dell, Windows 7
