I've searched the internet on how to transfer mp3 music files from my laptop to my Galaxy S plus, GB 2.3.3, can't find all the info I'm looking for. Connect the phone to laptop and 'mount', then go to My Computer and drag and drop...ok so far? I haven't tried this yet; does the phone's built in memory and micro sd card show up as separate drives and which one is it best to put the music files on? Does the main file containing the different song files require a specific name to be recognised as music for use as ringtones? Finally, how do I actually set up a song as a ringtone? I've installed Ringdroid in anticipation. Thanks.
