Android/iOS/Windows Phone: BitTorrent Sync is a handy alternative to Dropbox if you need a lot of storage space or don't trust someone else's servers. The mobile apps have been a bit wanting, but now you can finally create, edit, and share files right from your phone.
The new update which is rolling out today finally allows users to do more than just view their files. While some Android users could use a file manager as a work around, it was difficult. for other phones, it was impossible. Now, however, you can create and edit files, then save them to a Sync folder natively. This should make BitTorrent Sync a lot more useful on mobile devices.
