There are actually two methods we are going to highlight that both of which give good results, neither of which are the definitive tools for the job (the Windows-Mobile-as-iPhone community is surprisingly active). One method is relatively simple, the other requires a little more legwork.
After you've copied the files onto your smartphone, you can give it a quick test by navigating to the folder you've copied them to with File Explorer and running the launcher.exe. Launcher should give you the iPhone-like home screen. However, you will notice by default that the buttons on the home screen won't all point to something you can use, since each button points to a program, and some of them won't match anything on your Windows Mobile device.
