Hi, I'm one of the developers of Twitbit, an iPhone Twitter app:
http://twitbitapp.com As of about an hour ago, I began getting this error in response to every API request sent to Twitter: "Rate limit exceeded. Clients may not make more than 0 requests per hour." I get this for all accounts I have added to Twitbit. For what it's worth, Twitbit is an OAuth app, and if I fire up a different Twitter iPhone application that uses basic auth configured with the same accounts, I do not receive this error. I've searched for this error, and there are other people using other applications complaining of the same thing. Any help with this is greatly appreciated. Thanks in advance. John
