Waiting for delivery of my Defy and still not sure whether to root or not...Having read about a lot of UK models having the dreaded ear-piece fault, I'm just wondering: 1. what I can do that can be undone if my phone develops this fault? i.e. Is it possible to root the phone, remove some of the Motoblur stuff, overclock etc and still be able to return it to it's original state if the earpiece goes and I need to return it under warranty? (or at least make any mods undetectable!) 2. From what I've read it is possible to skip the Motoblur registration. Would I still be able to use the phone portal- what apps require the Motoblur registration? Basically I'd love to tweak the phone but am paranoid about voiding the waranty! Thanks in advance!
