I just got the iPhone and can't download a movie. Says it is too big at 50mb. Can anyone help me understand this. I have an unlimited download contract but was told this phone can't take a 50mb download.

New IPhone 5 I just got and I can't download movies from iTunes. I've been told it's because 50mb is too big for the iPhone.

Not getting much help. Is there anyone who can explain this problem to me?

I don't have access to wifi where I am and no problems accessing Internet from the phone when out and about. Just can't get the Apple store to download movies. :-(
