Do u have any idea if there is any version of Nokia PC suite, applicable to 3310 or so?

I try to update my phonebook through a non-official software that came with my data cable, but I receive various entry errors, which are different from time to time. I suspect it is due to incompatibilities between my greek language entries' (in UNICODE) and the software; but OK, there must be a solution.

Otherwise Nokia is completely completely idiot
