I got the notification for the update today and want to do it. Will I lose any apps or pictures on my phone if done OTA? I want to root to use titanium backup and start trying some roms out. I'm stock unrooted now, should I root after the update, and is it the same process as rooting 2.3.4? I really want to try the voodoo app to help my crappy external speaker, has anybody used it or have any comments on it? Thanks
