I have uploaded the iRadio collectors pack for v3.2 (the latest version). It includes a pack with 17 wallpapers, some instructions and MyPC.
Now, here's the new "news" (lol) : There's now available a eInstaller (easyInstaller), that simplifies the process of installing iRadio; you just need to select your PSP's drive letter, and follow the instructions. Everything else will be copied automatically. It can also install MyPC (and place a shortcut on your desktop), and can also copy the wallpaper pack from the collectors edition.
I can guarantee the program is safe and completely free of any kind of malware/spyware/adware/trojan/virus (because I made it and also because I have scanned it with Kaspersky Internet Security 2011; feel free to scan it by yourself as well).
All of these new downloads are available at the iRadio website.
