No fix for Korean Language Issue!
I wanted to let people know that if you have purchased an P3 in Korea and it wont change to any other language, then your player is probably like mine. Specifically, I had a P3PCB (P3 memories). I bought it online at a Korean store because it was $50 cheaper, it came with a case and a car charger.
I had to go to a Samsung service center where they tried to install new firmware but to no avail. They ended up replacing the memory/processor! This was totally free but a hassle none the less. I LOVE the P3 regardless but if I had to do it again, I would not have gone through all the trouble had I known this from the start.
