iTweet: Yet another iPhone Twitter client
In brief testing I did notice iTweet seems to run a bit faster than others, especially over EDGE, though Pocket Tweets still earns my usage and donation (scroll down for the Donate button) due to its top notch styling, ability to mark tweets as favorites and that all-too-increasingly-useful @ button for replying to someone's tweet.
Still, it's good to have options, and anyone obsessed with speed will likely enjoy the iTweet experience. For now, it appears iTweet is provided for free, as I can't find any kind of a donation button, so enjoy!
