Today evening I picked up my new phone on post office and as soon as I arrived home, I started to play with it. And well result for Gammu is poor, there is too much to implement. For now I only added identification, but I will work more on it.
Transfer of contacts was done by gammu --backup
data.vcs on old phone and then tranfering to new phone using
plain IrDA - ircp data.vcs. This is far from being
perfect - I lost most of text in extended entries, half of names is
also lost and I expect something might be missing. But I have at
least something till I will write full support in Gammu :-).
