Mp3 is a sound format whilst mp4 is a video format. Why would you want to do that?

Welcome to Esato

Use dbpoweramp software.

http://www.dbpoweramp.com

and download the FAAC codec from the codec central link on that page.

@universal - mp4 isnt a video format (at least i think it isnt) I store songs in mp4 format in my K700i.

Since you obviously can see the point in this, can you explain it to me who can't?

The point of mp4 is that the file size is smaller whilst maintaining the same bitrate as mp3

How smaller would a mp3 file become when converted to mp4?

It's nothing very dramatic. About 10-15% I think.

for me all my mp4's orginally around 2 MB (mp3) are now less than 1 MB. I use a low quality setting but i can make out only very minor changes in quality

Well on my brothers mobile (Nec e616), mp4 is a video format. So... I guess it's a video format

@Arez is right. I'm just not so sure that mp4 actually makes a file smaller if you use the same bitrate. I think mp4 actually has a much better psycho-acoustic model that when you use a lower bitrate like 96 or 80 you can achieve a sound that almost the same quality as a 128 Kbps mp3. In effect, for the same quality, mp4 can use lower bitrates so it uses a smaller filesize compared to mp3s.

You can use iTunes (AAC) or dbpoweramp to convert mp3 to mp4 as many suggested.
resistance is futile.

Bitrate is strongly linked with the filesize. It's a nonsense to say smaller filesise using the same bitrate. But you can say: same quality - lower bitrate.

blacksopt, in fact you should use the expression aac instead of mp4, because thatīs the name of the music format contained inside a mp4 with only music But this confuses ppl a lot
