I'm mightily impressed by all of Twittelator's features. If you're someone who frequently surfs around your friends' timelines and the public Twitter timeline, it's a better choice than Twitterrific. If most of your Twitter time is spent reading your friends timeline and posting tweets, it's not.
The good news is, all three of these programs are free, so you can download them for yourself if you're not sure about which one is right for you. (Unlike Twinkle and Twittelator, Twitterrific's free version is supported by occasional ads in the tweet list. You must buy the US$10 Twitterrific Premium to block those ads.)
And if you haven't updated your iPhone to version 2.0 (or don't want to download a lot of iPhone apps and risk stability problems), don't fear. Hahlo remains an excellent, full-featured Twitter client that works right within Safari.
All apps reviewed in this round-up are compatible with any iPhone or iPod touch running the iPhone 2.0 software update.
