i'm honestly worried you guys are going to break your phones somehow, when a step in the tutorial fails, sometimes you don't seem to notice and continue on... and then post some question about a problem 3 steps later instead. it probably doesn't help that asking too many questions gets you told off too. i hope you guys are fast learners because it looks like you loose either way!
i suggest you look up the commands as you type them in because you'll learn more if you know what is going on, and you're less likely to make a mistake. sometimes the instructions are not clear, and copy & paste can screw up too because you might not know where the line is supposed to start and end.
