I have seen some comments that people are having difficulty finding refresh button and new message indicator. The refresh button may not be at the most obvious location but it exists. Select a message and the bottom panel shows up. Touching the refresh button will refresh tweets.
The new message indicator exists on the top right on the message.
“Twitter is exploding fast and is a true global community. That’s why Twitter World comes so handy. You can easily translate the following languages to English and finally understand what everyone’s talking about on Twitter” - iPhoneAppsFinder.com
Twitter World has one spectacular function: it allows you to read Tweets written in foreign languages by automatically translating them. If you’ve been watching the news lately, you’ve probably heard of the events in Iran being highly integrated into the Twitter universe. Wouldn’t it be great to have been able to read the tweets of the Iranian protesters first hand? Too bad they were written in Farsi. That’s where Twitter World comes in. Also, if you just have lots of foreign friends, this app is perfect. - iSmashPhone.com

The tweeter has been a great force behind Iranian revolution. Google did a great job by quickly providing translation service for Farsi.
I am getting lots of tweets from people using my Application Twitter World - Breaking Borders to connect and read Farsi Tweets in English. I can easily include English to Farsi support as well but that will take more than 2 weeks to get through Apple’s bureaucracy 
In any case I am happy to support Iranian people.
I will like to announce availability of Twitter World: Breaking Borders for iPhone and tocuh. You can get it @ http://tinyurl.com/getTwitterWorld. I have seen explosion of Twitter Clients @ App store. However the TwitterWorld is different. It can translate tweets in to your language. No other Twitter application can do it. You can also use Twitter World to retweet in other language and reach larger user base.
