If you’ve ever wanted to download torrents on your iOS device, then iTransmission is the way to go. While Apple (currently) wouldn’t let something like this into the App Store, you can download it for free from the InsanelyI Cydia repo (repo.insanelyi.com). iTransmission is currently in alpha, so there may be some bugs. It’s very easy to use, works very well, and works for both the iPhone/iPod Touch and the iPad. For you developers out there, iTransmission is open-source.
