How to save attachment from Gmail? I've got two MP3 files from my friend via Gmail. How can I save them to my phone? There is only a Preview button...
Sounds like you have a crippled version of the app.

I emailed myself an mp3 file and got "Download" and "Preview" buttons. Pressing "Download" downloaded the file (as one would expect) to /sdcard/download.
