After months of searching and not finding a good solution, one presented itself. An orange promoteam came one day at the office to suggest a simple internet at home memory stick, working throuigh GPRS. It's 10 000 FCFA (about 15 EURO) per month, and it actually works better than what they have at the office. And it's so simple! Just a stick, you plug it in, they activate, and there you go.
So I've been blogging more often (if you hadn't noticed) and I'm enjoying the full facebook experience.
