Xcode 3.2 added the ability to rename projects. Choose Project > Rename Project.
Xcode is set to rename all files in the project that are based on the project name: project file, targets, build products (application name is an example), precompiled headers, and property lists. If you want to keep the old name for some files, deselect the checkbox in the left column.
