Okay, thanks.
My question is if this functionality is even supported if I were to upgrade.
Is there a way to use the aux-in only, and stop sound coming in on the speakerphone itself? Or do I always have to have sound coming in on the speakerphone?
You should be able to answer this question regardless of the state of the software on my phone, right? I don't want to waste my time upgrading the software on this phone if it's not going to solve my problem.
