I'm new to android..this is my first android phone. Im not rooted..running on 2.1 What do I have to do to change the theme? In the marketplace I saw a cool windows 7 theme but it said...(the app is by "diceman4") I need another app from the market but when I look for that app I can't find it. I guess its because at&t won't let it show Basically I would like to know how to change themes... do I have to pay for each theme? If I have to root then I'm out of luck.
