For the 4S, Apple has released 2 build versions of 5.0.1 firmware. 9A405 was the initial build number for 5.0.1 and the 4S. A week or two later they released 9A406 which said it addressed a sim card issue as well.
I am running 9A406 and that can only be installed via iTunes not via OTA like your build number.
Apple certainly makes 5.0.1 release confusing for iPhone 4S users.
