iPhone: If you're enjoying the benefits of HD video on your iPhone but wish you could actually send that video to others at full 720p resolution, Transfer Big Files lets you do just that.
Like many file transfer sites, Transfer Big Files uploads the file to their site and emails a download link to you or to whomever you're sending the file.
The app is pretty straightforward. Once you've signed up for an account, you just select the videos and/or photos you want to send, specify a recipient (it defaults to your email address), and send away. While I wouldn't say speed is its forte, it's an effective means of getting those HD videos off of your iPhone without plugging in.
