Transmission is a BitTorrent client for Macs, and for a brief time in January 2011, iPhone users could manage their BitTorrent downloads remotely using the iControlbits iOS app. That included the ability to add new files, pause existing downloads and adjust server settings.
Violation: Although iControlbits advertises the management of “legal downloads,” BitTorrent’s association with piracy likely sealed its fate in the App Store.
Jailbreak Alternative: iControlBits is still available through the BigBoss jailbreak app repository.
