I'll do this probably next week. I'm new to Android (iPhone 3gs before this) so I'll explore around before this.
Best to just get it over with soon, since after rotting/flashing it wipes all your stuff, but you can easily backup/restore it all and it's a quite painless process.
You're going to LOVE IT! I loved switching! Never going back to iPhone again!

hmm. i have the lte version. i like it. not sure whether to root though, doesn't that void your warranty?
Rooting (not sure), but Flashing a ROM voids warranty yes. I think there is a way to do it without voiding, but I don't really care either way. Software wise It's really hard to brick because you install a 'Custom Recovery' in which you can always boot to before the ROM so you are pretty much un-brick-able.
