With more and more cellular providers going to a set data amount, uTorrent thought they'd lend a hand increasing carriers' profits by releasing a mobile torrent app. BitTorrent Inc., the creators of uTorrent, have released a beta mobile uTorrent app that allows torrents to be directly downloaded to a user's phone.
As the app is still in beta, many features are still missing and performance is likely a bit lower than what it will end up being. But, there is one feature that works: downloading torrents. Downloading torrents works over a 3G or 4G connection, but doing so will likely use up all of your limited data.
If you happen to be on an unlimited plan, torrenting will probably get you a letter from your carrier saying your usage is too high and they are going to cancel you. The Android app is supposed to provide access to legal content, but BitTorrent Inc. has yet to add that feature. They hope to grow their mobile user base with this new app.
