Mac: iOS blog iDownload Blog found a hidden feature in Apple's new Messages app that allows you to send any file type between your Mac and your iPhone instantly. The iPhone can open video, text, photos and music, but the files are stored in a folder that can be accessed on a jailbroken device.
In Messages on the Mac, you can drag any file to the message window and send it directly to iMessages on your iPhone. The iMessages app can open the same types of files as Mail can, but if you're jailbroken, you can navigate to the /var/mobile/Library/SMS/ folder and grab any file in a file browser like iFile. It's a feature that might come in handy if you quickly need to swap a file between devices and don't want to use Dropbox or email.
