Wak,
Nokia like to do their own firmware upgrades via their network of Nokia Service Centres. If you find the nearest to you, ask them if there is one available for the Nokia 6230 yet. Certainly for their other smartphones, they have been providing firmware upgrades although they like a reason before prescribing one (if it ain't broke don't fix it..)..
Siemens has a more DIY attitude to firmware upgrades, and posts them onto its website on a regular basis with the necessary firmware flashing software (for SX1 and others).
Thanks for the tip on blank label to help with NAM recognizing the MMC. Will post that up in separate article to help other 6230 owners if OK by you Wak.?
sure no problem always willing to help!
