I did one to see if it will fix a issue i had, after i done it i realized i should have checked first.

Does a reset lock the phone back up? It was unlocked. I wouldn't know at this point cause i'm on att on a att phone but i might have to switch later on.

Also i can't seem to find how to turn off the noise when you punch a key on the keyboard. I turned it off before. I'm thinking it's supposed to be under the sound tab in settings but all is unchecked but when reading there is no choice of that sound.
