I have searched this forum with no luck, so I'm asking for input. I have, and love a Galaxy s2 Skyrocket that was customized and is now a T989. Over the 3 years I've owned it, it has worked flawlessly on T-Mobile 4g. I would like to upgrade the OS. I have also purchased a factory unlock for the phone over a year ago, but never used it. Below is ther content of what I am running. My question is, or should I say are, what phone do I own, and how would you upgrade its operating system? Would you factory unlock it? I don't want a new phone as this one is a perfect size. I do appreciate any help, and if I missed where this was posted on this site, I apologize.

If this is too cpmplicated, I get it. Your time is important but I had to ask as I couldn't figure it out, and I'm pretty techy otherwise.
