It’s the “autorun” trick.
Basically, create an autorun.inf file on your device. It’s basically a text file with an .inf extension. Inside the file should be:
[autorun]
icon=my_icon_file.ico
label=My Cool Device Name
I believe the icon parameter will take a BMP file too but it’s best to make your own ICO files with multiple sizes so it looks good in different resolutions. I made 16x16, 24x24, 32x32, 48x48, 64x64, 96x96, and 128x128 sizes just in case. There is a limit for the length of the label but I’m not sure what it is yet.
I’ll make a black iPod nano icon to go along with the white one and post it here just in case you guys want to save some time. I’ll also upload the MZ-RH10 and NW-E507 ones too just in case anyone else wants them.
[EDIT]
Ok, I’ve uploaded the iPod nano files here . Simply unzip the files (with included directory) directly onto your iPod nano. You’ll want to use a text editor to edit the autorun.inf file to change some of the settings. To uncomment simply remove the semi-colon. Enjoy. Sony ones coming soon…
