I just got the BB Storm on Monday. The first application I downloaded was Twitterberry. This morning, it worked fine. But when I check it later it says "Your request was invalid or rate-limited". I don't know what that means, I just know I would like my twitter back. I deleted and reinstalled twice to no avail. Suggestions/help?

go into the menu and configure and test the connection

If it still doesnt work, you can always check out twibble @ twibble :: a location aware twitter client for Mac OS, Windows, Mobile which is another great mobile twitter client.

I would recommend the mobile sites that integrate with the twitter API rather than an app - try dabr.co.uk or m.slandr.net or even the m.twitter.com site in preference to an app
