Tip for obtaining product codes
As those of us who have changed the product codes on our 5800's using JAF etc know, one of the main problems is obtaining the correct product codes to obtain the latest updates. Google "Navifirm" and download it, runs quite nicely and gives the latest firmware versions and product codes for every Nokia phone. I would post a download link but I don't have one, had to join a forum to obtain it directly. Sure that a bit of googling will find a download link, and then you'll never have to look for a product code again!
To quote the developer:
"NAVIFIRM is the ultimate all-purpose tool for downloading Nokia firmware images, obtaining lists of product codes, and finding the right product code for your phone. NAVIFIRM downloads all this straight from Nokia's servers so you don't have to wait for people to post data packages and lists of product codes.
NAVIFIRM is useful for just about anyone:
End users: Find product codes to use with NSS/NSU
Journalists: Be the first to know when new firmware hits NSU
Developers: Download ROM images for extracting files
Care Suite/Phoenix/box users: Download ROM images to flash
Additional NSU servers can be added by editing Main.cs in the source code."
Used it about an hour ago again, found the product code for which the latest firmware version for the 5800 had been released (31......), changed the code (0552438) (Red, British Isles) and presto, new firmware available via NSU.....
Hope this helps
