I finally ordered new phone for me. I decided to buy it together with switching to T-Mobile as they offered quite good price (and I want to switch anyway).
It will be Sony-Ericsson K750i, so you can expect increasing support for Sony-Ericsson phones in Gammu and Wammu. My goal is to have simmilar feature set as FMA has, what I think should be enogh for most of phone users :-).
