A couple of months ago we posted on a jailbreak application for the iPhone and iPod touch called Twinkle. Twinkle has just debuted on the App Store and might give Twitterrific a run for it’s money with the ability to location-base your tweets.

Critics say Twinkle is better than the mobile version of Twitter, better than Hahlo, and better than MobileTwitter. It supports photos with your tweets, taken right from the iPhone camera, as well as geolocation. There is also a “Near Me” section that will show you other Twitter users in your area.

While Twitterrific seems to have more precise locating abilities, Twinkle uses the location-based tweeting in interesting ways. For instance, you can see tweets originating within a certain mileage range from your location. Twinkle also allows you to easily view your direct messages.

If you’re unfamiliar with Twitter or are bored with reading tutorials, B.E.T.A. Daily has put together a handy collection of videos that demonstrate various uses of Twitter.

Perhaps the best new of all is that Twinkle for iPhone and iPod touch is absolutely free.
