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 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

Update: The updated with fix has now been accepted by Apple is now @ AppStore. Get it
My previous release of Twitter World application had a nasty bug which made it unusable for lots of “Twitter World” users and completely killed the reputation. I owe these users an explanation of what happened.
As you know, Twitter World uses Google API to translate Tweets. In version 1.0, the Twitter World translated one tweet at a time. This was slow and resulted in significantly slow initial load time. So I decided to use the newly available Google batch translation API. The batch feature of the API allows me to submit multiple translation requests at once. Google also has a limit of maximum 2000 encoded characters in the URL. A given batch could have at most 7 tweets. Any given tweet cannot be more than 140 characters long. So in theory this should always have been safe.
The part I missed was UTF8. In UTF8 (which is the most used character encoding), every character can be encoded in 1-4 byte. Now if you take 140 characters/tweet and mutliply it with 4, you get up to 560 characters in the URL per tweet. That implies even 4 tweets can take up to 2000 URL character limit Google requires. This results in URL too long error from Google.
This along with some lousy error handling caused the crash which a lot of users saw with the version 2.0 of the Twitter World. The fix was uploaded to Apple yesterday. It is frustrating that I cannot push the fix out faster and am @ Apple’s mercy when it comes to pushing update to this critical issue. In the middle if somebody needs an update, I can provide them with ad-hoc release.

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.
