You can listen to Last.FM on your iPhone, G1 and your PC/Mac but you can’t have mp3 files. With Last.Fm Downloader you can! It’s free and has no spyware, viruses.
FYI:
Last.FM downloader is pretty much illegal to own because you are downloading songs that are copyright material, but I am sure you have P2P software such as LimeWire, Strong DC++, Kazaa etc…
Use it at your own risk.
Currently this is only supported in Windows.
