I own a Nokia 6102i phone (provided by Cingular). gnokii is a Linux program that lets me interface with the phone. Here are some recipes:
gnokii --getfilelist "A:\\predefgallery\\predeftones\\predefringtones\\*"
gnokii --putfile WiiSports.mp3 "A:\\predefgallery\\predeftones\\predefringtones\\WiiSports.mp3"
Voice mail picks up in 20 seconds, so a ring tone should be about 20 seconds long.
The easiest way to chop an MP3 in Linux is with dd; the drawback is that you need to specify length in KB, not time. To chop an MP3 to be 200 KB long, do:
dd if=Mii\ Channel.mp3 of=MiiChan2.mp3 bs=1k count=200
To make a Phonebook.ldif file from the phone (suitable for import into Thunderbird):
gnokii --getphonebook ME 1 end --ldif > Phonebook.ldif
To add the entries in Phonebook.ldif to the phone:
cat Phonebook.ldif | gnokii --writephonebook -m ME --find-free --ldif
You can specify --overwrite instead of --find-free if you want to overwrite all the entries, but this will lose some data (e.g. speed dial, preferred numbers).
You can get photos like this:
gnokii --getfile "A:\\predefgallery\\predefphotos\\Image000.jpg"
They are 640x480 JPG files. (You can also configure the camera so that it takes pictures at 80x96.)
You can also store files:
gnokii --putfile silly.jpg "A:\\predefgallery\\predefphotos\\silly.jpg"
These show up on the phone in My Stuff/Images. The files don’t need to be any specific size; they are autoscaled. GIFs probably also work.
Videos live here:
gnokii --getfile "A:\\predefgallery\\predefvideos\\Video000.3gp"
VLC seems to be able to play .3gp files, but the audio doesn’t work.
Audio recordings live here:
gnokii --getfile "A:\\predefgallery\\predefrecordings\\Audio000.amr"
Unfortunately, nothing I knew of in 2007 (when this page was first written) would play .amr files, but these days (2021) perhaps ffmpeg input.amr output.mp3 would work. You might have to use the -ar flag to specify the audio rate. I haven’t actually tried this though!
