couple of questions (screenshot attached)

[chasen]

I bought my Tab new (sort-of). Bought it from a guy who purchased it, rooted it and did other stuff (that i don't know) then sold it to me.

attached is a screen shot.

Questions:
what rom am i running?
what kernel?
how do i change these as there's no rom manager installed?
what else can you tell me from the screenshot that is important?

thanks in advance!!

Based on what I can see and someone can correct me if I'm wrong, this is what your running. The Gingerbread.EF17 is essentialy a stock Sprint Gingerbread update

If you wanted to possibly install another ROM you would do it through a recovery such as CWM, or some variant. Someone else can surely elaborate further into this. I have just begun messing my with GT.

Hope I was of some help, dont have my tablet on hand to compare with yours, but could check when I get home
