I was at Walmart today looking at the Straight Talk GS2. It's still got Gingerbread.

Can I root and upgrade to Jelly Bean? I like JB a lot better than GB. Is there a ROM available to flash--or would I even need a new ROM?

I would like to know this as well

S2 has already got official jelly bean rom from Samsung. So most likely you can upgrade it directly from Samsung with kies. If that failed, and the phone is international version you don't need to root it to Flash jellybean. All you need is odin and official jelly bean rom from Samsung which are widely available in sammobile. There's are also many third-party rom available like CM rom.
