This sounds like your device might have some hardware issue with the earphone jack.
Regarding this 'update', the most recent update is the MF3 build OTA update. You should have this by now, if you don't, be careful. You can update to it but if your phone is rooted or you plan to root - you need to search the threads of maintaining or gaining root access. The MF3 OTA update did a number on some people when it relocked bootloaders.
You can attempt to find this via Kies or you carrier.
