Okay so my Droid x2, is currently running Android 2.3.4 and I'm wanting to root my device. I may, probably not, (correct my lingo) flash a modded firmware? I plan on following This guide and rooting my phone, now to me it looks simple to unroot, just clicking the unroot button, but whats all this about Freezing/Deleting apps? Do I have to do this? Also how do I make sure my contacts are back up in case I do decide to unroot? Also what is Bootstrap, do I need that for recovery? Where do I get it if I need it?
