So, a friend of mine is willing to trade his SGS3 for my Razr Maxx. I do like my Maxx, but ever since the OG droid I've loved the openness that comes with unlocked bootloaders (which, of course, isn't available with the Maxx). I wanted some opinions from others on whether or not I should go through with it (I've been thinking about it for quite some time). Main things I want some opinions on: 1) The Maxx obviously has a bigger battery, but I've heard the SGS3's S4 chip gives it somewhat comparable battery life regardless. I'd like some thoughts on this. 2) If you've owned a Razr and switched to an SGS3 or vice versa, how would you rate the user experience in comparison? 3) How is the call experience on the SGS3? I was also wondering, if I do trade, will I be able to just pop my microsim in the SGS3 and go? Or will I have to call the usual *228 and set everything up using that method?
