I'd recommend Lenogo Video to iPhone Converte to you,It automatically converts almost all formats of video files that are already on your computer (AVI, MPG, MPEG, ASF, WMV, MOV, 3GP, AMR, FLV, FLIC, SWF, RM, RMVB etc.) into a format that\'s compatible with iPhone video, that is, iPhone mp4 format.
So I recommend you this tool,you can see detail and free download it here: kooksoft.com/software/MobilePDA/iPhone/200807/17-116.html
