I've been using TouchTwit... still not sure that I like it better than PockeTwit. One of my main issues is also that it has no sound notifications for new tweets. It's not a bug, it just does not have this functionality! (Although it does have notifications for Mentions and Direct Messages.)

Still, I'm sticking with it as the developers seems to be updating it on a regular basis and I hope it continues to improve and add additional necessary features.
