Just so we're clear, I know basically nada about the inner workings of Unix/Linux/Android.

Anyway, I bought my first smart phone a little while back, a Sony Xperia Arc, and despite being in mortal fear of the outcome I've decided I want to root it. I thought I'd use SuperOneClick since it seems to be both popular and as idiot-proof as rooting tools come.

What I don't know though is what happens after I've rooted the phone (while hopefully avoiding bricking it).

1. Can I still update the firmware in the regular way? ICS is right around the corner for the Arc, so if not I'll wait until it's out.

2. Does rooting affect installed apps? In other words, will I have to re-install stuff after the phone has been rooted?

Your assistance will be very much appreciated!
