i have a strange problem.
i have a jailbroken 3gs
and i am trying to download movies from mobile theater

i have dtunes installed with ifile and safari download manager. etc

mp3's download and save fine over my 3G just fine. but movies do not ever download unless i am on wifi

movies will not download over my 3G

torrents also only work over wifi with iterminal and not 3g
when i am connected to wifi it works perfectly. what is the problem here.
