The folks at popular Twitter image uploading service Twitpic released their own app today on the App Store. The app allows you to easily edit photos with a number of filters and other effects, such as cropping, brightness, and orientation. Twitpic for iPhone also offers the ability to view all pictures and videos of the people you are following on Twitter, as well as the ability to comment on Twitpic pictures, and the option to see the most popular pictures shared on Twitpic for the day. You can check out the new app here.

Furthermore, there is also some nice app updates today: SoundCloud has been updated to version 2.1.9, which features a fix for an issue where users could not navigate after signing up/ logging in—definitely a bummer. For those of you who use the Wall Street Journal iPad app to find your daily news, you will be happy to learn that the app gained Retina display support, which is just perfect for the new iPad. You can grab the SoundCloud update here, and Wall Street Journal update here. A few others include: a Washington Post update that can be found here; Madden NFL 12 here; and, TNT for iPad here.
