So i'm new to the Android community. Jailbreaking an iPhone was way easy and i'm under the impression that rooting is pretty much Android jailbreak. So, what exactly is a root? Once i've rooted and I install a ROM, what if I have to send my phone in to Google how do I restore it to the original firmware? What do I need to download to make my N1 look like Desire's Sense UI? Is there just like a big guide that tells you how to do all that stuff?
