The Blackberry browser has a 2.5MB download limit so a movie won't download using it. Try using either Opera Mini or Bolt Browser. They may work better.
if you want to know exactly how large the file size is, it is about anywhere from 300-1000MB.
I doubt the speed of any Blackberry could download a movie OTA in good time (a few hours at least)
Ya used to be able to download movies via opera mini. I updated my storm os and upgraded to opera 5 and now I can't. I'm not sure if its the os or what cause I've tried installing other versions of opera again and now nothing works.
As for dl time being slow. I dl'd movies faster on my phone then I could on my comp. Takes about 3.5hrs on my pc and about an hour to hour and a half on my phone.
I download every leaked os that comes out ota from my berry. Just google search for "unlimited download size blackberry". You can download any type of file, but megauplaod, u have to put it into column view in order to be able to click the download link, fyi.
