Today I tried for first time software for Sony-Ericsson K750i on Windows. The supplied Sony-Ericsson suite offers only sync, when I try to browse files, it says phone is not connected. Okay, usual manufacturer software quality, I didn't expect more :-).
Next I installed floAt's Mobile Agent. I read quite good reports about this software, so I had to see what competition does Wammu have on Windows :-).
After some troubles to configure phone connection, including some Windows restarts, I managed to download some data. I was very suprised that my contact names weren't correctly decoded (in vCard they're properly in UTF-8). Rest of support is on very simmilar level as in my Gammu branch, Wammu is still far behind, especially in GUI design.
