Ok, so I've never rooted before and after quite a bit of research I'm just about ready to make a go at it. However, I've noticed something. After the last OTA update to 4.04, my bootscreen shows the little unlocked lock at the bottom. I was under the assumption that that only shows when you've unlocked your bootloader already. However, I've never made any such alteration to my phone. It's been stock since I bought it on the day of release. Is this an odd glitch, or is my phone unlocked and ready to be rooted already? Thanks a ton for any help.
