Some questions

[g8gt2012]

OK, I know there have been 2.1 threads with questions but I am still a little confused and couldn't quite find the answers to my questions and so I don't hijack someone else's thread, or lead to it being hijacked, I thought I'd just start my own. So here are my questions

OK I rooted about a week before ESE81 was released and am running BB .9, I have seen posts about installing the 'Nexus Mod' but can not find this anywhere. What exactly is it and what does it do?

I have been thinking about unrooting to install ESE81, if I did this is there a why to return to being rooted? I know that Pete has a guide to install a rooted ESE81 but I'd rather do the OTA.

If I went to a rooted ESE81 would I still be able to use BB .9 or any custom ROM?

Thanks in advanced for any and all help
