hello all! i recently purchased a brand new macbook pro and i love it! long time user of the iPhone. i still have lots to learn about this. I've been using pc's for the longest time and i figured it was time for a change. one question tho, i saw that theres themes i could download for my pro and i was wondering if i needed anything to use them. like, how the iPhone has winterboard and thats where you go to change themes and such. also, is there a way to download free 'iTunes' apps like what installous does..?
