Will iMovie upload/render videos from iPhone 4 in 720p?

I keep asking before MY PARTNER AND I buy them if it is going to save being a HD video and publish to Myspace in 720, unlike importing straight from your camera spin.(iMovie with the iPhone FIVE btw)
Gives thanks.

Yes, primary just move the video clip from apple company iphone 4 for you to iTunes along with imedia airport transfer for Macintosh personal computer, then in your iMovie.
