TwitPic, which was the first photo sharing service for Twitter (and probably the most popular for a while, at least until competing services like Instagram stepped up) has finally released an iPhone app. It's ill-timed to say the least, considering that Twitter now has an official service (built into the official app and Apple's iOS), and several third-party apps hook into TwitPic.
But if you remain a big TwitPic user, the free app is probably worth grabbing. You can manage and upload your own photos and videos, and browse others' content as well. It may be a little late, but for those still making use of TwitPic's service, this app should come in handy.
