Well for starters, the OTA that came out last week was 42.2 mb, this New Update is 76.9 mb, only confirming what was stated above that it replaces everything.
I for one need to downgrade and then reupgrade with this NEW Update.
My phone has has been real sluggish after last weeks update, have not seen one part of smoothness people are talking about, when my phone goes to the main screen it takes a few seconds for my items to show up, I get lag when typing (entering passwords sucks), and now i'm having random restarts, not saying that part is from last weeks update, but I need to start from scratch regardless.
And I think some of the problems I have is the reason why VRZ, or who ever made this update version a CLEAN INSTALL.
This is going to suck, because I hate 'RSD Lite' ever since my RAZOR days, it can F-Up your phone in the matter of seconds..
