Here is a guide on how to theme CM7 to look like Ice Cream Sandwich. Make sure you are rooted. You're going to want ROM toolbox installed to make this go smoother. Step 1: Download ROM Toolbox, Ice Cream Sandwich (theme) by Kovdev, Ice Cream Sandwich CM7 Theme by Sonny, and Go Launcher Ex or ADW Launcher Ex (If you want to buy it) from the market. Step 2: Open Theme Chooser and select ICS. Step 3: Open ROM Toolbox. Select Interface. Then select Font Installer. Select Roboto. Select Install. Step 4: ADW Launcher Ex: Open Ice Cream Sandwich (theme). Select apply theme. Under Icons choose Ice Cream Sandwich. Under Main Dock choose ADW Theme and select Ice cream Sandwich. Go Launcher Ex: Open Ice Cream Sandwich (theme) and select apply theme. Choose the same things for icons and dock. Just like ADW ^^. There you go! It should look something like this.
