The problem: The music I have on my phone only plays through the right speaker. Through all devices such as: Blue tooth (it only plays from the right speaker in my car), and even with auxiliary input.
My question: I have a friend who had similar issues with his phone, and he told me to go into my local store and ask if you would be willing to replace it for me. Where as my concern lies in the fact that my phones "insurance" is through Best Buy's Geek Squad (which I am happy to change to Verizon if they're willing to/can help). Whereas, I need my phone for work, since I'm constantly being talked to by my employees; none of Geek Squads options were viable.
Your phone is less than 1 year old and still under Apple's warranty. Your best bet for acceptable solution is to make an appointment at the Apple Store, if you have one nearby, and have Apple handle it.
