There’s a Dutch update for Orange SPV C500 users here at Orange.nl (direct link). There is an information page, however you’ll need to log into the Dutch Orange site with an SMS to register. The link above appears to work without needing to log in however.
Marc Verschoor emailed me to say…
“I installed the update, which went smoothly. Phone is working just fine. In this release, you can indeed use all audio media types for your ringtones.”
This update brings the Dutch Orange C500 up to version 188.8.131.52. Don’t forget that you should ONLY perform this upgrade if you own a C500 which was purchased in the Netherlands.
