FacebookThis allows instant Facebook uploading from your Photos app (Cydia)
A new Cydia tweak has been released called FacebookThis which allows you to upload images to your Facebook account directly from your photos app. There has been much speculation about Facebook being integrated into iOS6, but with no official announcements as of yet surrounding the release of iOS6, this new tweak will give you a feel for what Facebook iOS integration might be like in the future.
FacebookThis comes with no extra icons or settings, it simply integrates seemlessly into the photos app share menu. After installation you will see a new option for "Facebook." The tweak even allows you to input a caption for the photo. Like other apps that use the Facebook API, you will have to authorize the app through Facebook on the initial launch, but after that you can upload freely to Facebook as you please.
FacebookThis is available in Cydia from the BigBoss repo and it is another free tweak!
