Nokia allowed people to receive 72x14, 1bpp pictures over a series of binary- or hex-encoded SMS messages, and have them show up instead of their carrier name on the home screen. In the 2000s, magazine ads and webpages would distribute them using premium-SMS.
This service, also featuring ringtones, games etc. has been revived, free of charge, by MtF hacker @[email protected] of the Chaos Computer Club. You can go to Blåmba.de and download all kinds of content into your retro phone.
The service has been discussed in detail at her 38C3 talk: media.ccc.de / YouTube mirror
I also made 10 logos mostly related to Blåhaj, these are already in the Blåmba logo repository.
I welcome feedback and suggestions for future logos!
shit this is so cool, these phones are all pre-4G though right?
Yup. This will not work on Android, iOS or “post-J2ME” feature phones. However, we still have 2G in most of Europe so the old phones can be and often are still used.
