rotate a 3gp file

hi - i have taken a video on my mobile phone but it was the wrong way round. is there a way to rotate this clip in either quicktime or imovie (quicktime prefered) without upgrading to pro? a plugin or something?
i have an intel based mac if that makes any difference - quicktime 7 and imovie 6
thanks a lot!!

Import it into imovie and use the reverse effect, then export ("share") it.

not sure if you figured it out yet or not but i saw this and thought i would share:
