Zipcar, Tweetie 2, EyeTV iPhone apps have us titillated

There are three in particular that caught our eye lately, including the long-awaited Zipcar app, Tweetie 2, and the first release of EyeTV for iPhone. Though two of the three require laying down some cash, we think the feature sets are worth it.
