This just in:
The discount codes of the N810 maemo contributors program are going to be valid from today onwards in the supported Nokia shops. Some of the shops might not have device in stock yet. If this is the case of your country please be a little bit (more) patient.
[List of Shop-URLs]
Remember that your discount code is:08154711. The code will be valid until the end of February. Please keep it in a safe place since this is the last time we will send it. If you have further questions please contact the customer care channel of your shop.
We had to make some changes in some codes. In case the code listed here is different than the one you received, this is the good one.
Yepp, I can certify it’s working as good as the older one to produce, using the link supplied:
Ihr Aktions- oder Gutscheincode ist ungültig.
WTF? “The discount codes […] are going to be valid from today onwards”, did I do my English wrong in anticipating that “from today onwards” means after receiving the email (which was already delayed a bit due to greylisting) the code should be working?
Come on, Nokia, what’s going on here‽

…it seems that they’re using different service providers. More places were things can be messed up.

So where are these funny pills my doctor gave me…
