Unable to upgrade my Ios Phonegap build version for next release

I have already uploaded a build to ios-appstore of 3.0.4 version. But i now want to upgrade it to 3.0.5 as i had made changes to it. I have changed my config.xml in phonegap ios project.

<widget id="com.xyz.abc" version=“3.0.5” ios-CFBundleIdentifier="com.xyz.abc" ios-CFBundleVersion=“3.0.5” android-packageName="com.xyz.abc" android-versionCode="3052" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0"> 

But I am facing an error while upgrading the build and it says, "the build version 3.0.5 already exists"
