So I am in the market for a micro SD card for my 8320 and been doing some research on what is available. Imma music/junkie so I would prefer getting the biggest card available which I believe is the 12g.

I have learned that with my current OS 4.2 I can only use 4g cards but the higher OS 4.3 can use 8g or even more.

What I would like to know is which OS will be necessary in order to use the 12g card and how would I go about upgrading to that OS? I have been unable to find any answers to this question while browsing these forums so I was inclined to make my first post.

Thanks in advance.
