Is all you do get summerboard from he installer app, i saw some people said this was screwing them up, is this what summer board lets udo, change ur backrounds and what icons look like, i am already able to scroll to have more apps, a little info would be great, thanks! BAsically my main question is, does it srcew ur ipod up with all the apps and stuff as i was seeing earlier or is it perfectly safe to download and does it let you do all that cool customization?
