I've been trying to add ringtones to my Sigmatel FXD S9000. I've received a
2GB micro SD card which works (SDHC doesn't), and I can play MP3s but not
MIDI files in the file manager. I can't seem to find an option to take
ringtones off the card (the phone has a single built-in MIDI ringtone in
addition to a single non-MIDI ringtone). It has no other I/O (no Bluetooth,
no USB) except the air interface.

Anyway, that set me wondering how ringtones are delivered by commercial
services. You text the SMS shortcode and it debits your account by 5 pounds
or whatever. How does the ringtone then get into the phone? Presumably you
can do it by MMS. Or sending an SMS containing a link to a WAP site. But
what happens with phones that don't have WAP or MMS? I'm sure ringtone
suppliers have been around longer than WAP? How did it work in the old
days?
