I got a very very early version of the 6280, and the firmware was very buggy and a couple of weeks ago it ceased to be! Died. Took it to Phones4u and they sent me to some club nokia repair store where they upgraded my firmware to V 3.7 which is super EXCEPT:
When you add a word to the dictionary, the word will work in that session but as soon as you go to write a new text the word is gone and you have to manually type it in again. This did not happen in the earlier firmware version so it's strange that it happens now.
Hope you can fix it! Is there any way we can upgrade our own firmware without having to take it there?
