I received the OTA update a couple days back and updated the OS. The build number now shows ITL41F, which i believe is what it should show once its updated. I never experienced the serious volume problems (in-call volume drops, rapid fluctuations etc.) but i have been having a minor one, which has persisted even after the update. While using GTalk, almost every time i receive a message, the volume drops. I got a volume locker app for now which works well, so its not really a deal breaker. I was just wondering if anyone else has experienced this.
