So I installed Rom Toolbox to use the ad blocker, after I set up the ad blocker and the hosts file was installed, my 3g started constantly cutting in and out, I couldnt use it for more than a minute. But then I went into /system /etc and deleted the hosts file, and my data has stayed connected all day. I don't know if this is already known, but I just wanted to post what happened to me and see what people thought.
