Twitpic

Twitpic is Twitter's official iPhone app that lets you share your photos directly on Twitter.

First, twitpic allows you to edit your photos before publishing on twitter. You can resize them like, rotate them, adjust brightness, and even apply different filters that are similar to Instagram's.

In addition to photos, Twitpic allows you to record and share the videos displayed in your timeline, and copy from the application.

Another advantage of twitpic is that you can see the uploaded photos by the application's most popular users, which allows you to follow new people to follow ... or not.

Twitpic is a great application with many advantages. The only problem is that there are already numerous applications for earning the same thing in the iPhone. Still, it's definitely a try, especially if you've used Twitpic before.
