jailbreak for low call volume problems?

[gmaddog]

I've been having trouble hearing on a new iPhone 4s. Yes, the call volume is turned all the way up and the plastic cover is off. SoundCheck is off, too. I'm at the point where the only thing I know to do is to jailbreak. I have to do something, but I am not a tech wizard and jailbreaking seems a bit extensive. Is there any guidance someone can give me about what to do? I use a Windows PC and was looking at redsn0w, but again, I don't know if this is a radical step to take just to make my phone louder. I don't really need it to be jailbroken for any other reason. Also, it seems like a lot of people are having volume problems, though weeks of researching this issue.
