I need to transfer a movie file from my computer to my iphone?

But I don't have my usb cable until monday. Any way I can transfer it?

Buy one from Walmart.

Maybe icloud? I'm not a 100% sure what it does but I think if you set it up you can just send things from computer to phone

Transfer it via your Internet

Use HFS(Http File Server):

1.Allow it through your firewall
Once it runs right-click and add files or folders if it's a folder select the option "Real Folder" as it's faster.

2. Select Menu / IP Address/ This is the IP you will use on your Iphone to get the files
example: http://192.168.1.113

Find 4easoft iPhone manager. It can transfer files from computer to iPhone or from iPhone to computer.
