Root Official ICS update?

[obsidianwings]

Hi,
I just bought an atrix 2, I meant to update to ICS before rooting but unfortunately forgot, I have succesfully rooted, however, is it safe to accept the OTA update at this point, or am I stuck with GB?
Also, how do I make a nandroid backup on it? My last phone was an lg p500, so when I rooted I had CWM, that doesn't seem to work on this?
Thanks

My problem has slightly changed now, google suggested it wouldn't brick my phone so I went ahead and updated, it broke my root obviously, however I am having trouble rerooting :/ it keeps hanging at daemon started succesfully. Any tips?

Never mind, solved the problem. In case anyone else has this problem in the future, just factory reset and then root again.
