Click to viewThere are a total of 552 different apps in the iPhone App Store right now. We're going to do live impressions of the best ones (and some really, really lousy ones if they're interesting enough). UPDATE: It's over! More at our iPhone App coverage..
Twitterific: Works just like the desktop version of Twitterific (it gives you access to Twitter), and also uses the iPhone's location-aware features to geotag your tweets. What it doesn't do, like Twinkle, is give you a feed of Twitter users from around you. It does, however, let you attach photos to pics and let you know if your friends Tweet from a nearby location. Overall, pretty good. Ad-supported version is Free; Ad-free version is $10.
