Does newest N80 firmware fix T9 dictionary bug?

Question

My N80 firmware has been updated already twice in my local service point (Finland) for the same reason: in some phase of usage it stops saving new words to dictionary.
When writing SMS and entering a new word, it remembers that new word during the same message writing. When opening a new message to write, the word is no longer in use (not included in dictionary's suggestions).
First firmware update didn't fix the problem - I keep thinking because I restored a full backup from memory card - maybe restored also faulty dictionary file?? Don't know is that a file that is includes in full backup.
Second update: I didn't restore anything and "teached" the new words all over again. Now the dictionary has stopped working again!
I checked my current firmware: 4.0623.0.41 (build 26-07-2006)
Ran software update availability check: available version 4.0623.0.42 (build 20-09-2006).
I really wonder why my local service point hasn't put the newest firmware for me, think this new version has been out ages ago (yes, I do realise that build date is different that release date). These firmware re-installations (because the version hasn't changed from the version which was on the phone when I bought it on April 07) have both been done after May 2007.
Now, the question is, if I go to the service point, should they have this version 4.0623.0.42 available to my phone? The second time (in June) when I asked the newest possible version, this .41 was installed again - so can someone from Finland confirm if this new .42 has delivered to service points? Hate to go nagging there if they really don't have it
And more importantly, (and to this I like to hear the answer from Nokia personnel or from users who have been experiencing same problem) will this firmware version fix this problem? Either
a) keeps saving words
or
b) gives a proper error if saving is not possible for reason X
In my case it could not have been "not enough memory/free space"-error, because I have plenty of free space in both, phone and memory card. So if the error comes for some other reason, like to know why.
And no, I won't try to update firmware by my self. I tried it once and my phone died So no trust from me to that service.

Answer 1

I don't believe her claim unless it was true and valid up until the N95. I pass through Wales an awful lot during my work day and therefore I have many many Welsh town and place names entered into my T9 dictionary, along with other words I have added and the few custom smilies I added to it, it has to have way more than 30 words in it.
I'm aware of a bug that resets the T9 dictionary every now and then. The word file gets overwritten every so often and your words disappear. Never did find out what caused it but it affected the 6680. Perhaps this could be the problem.
