Best format of music for my Sony Ericcson j105i Naite?

I got my self a Sony Ericcson J105i Naite with a Sandisk 2GB microsd. I would like to put my favorite songs in to the phone so i can listen to them on the go. What will be the best format? Bitrate? is it aac or mp3?, Any recommended tools to use? like converting my current mp3 to aac or whatever other bitrate or format that you guys recommend!. Thanks a lot.
