Post length bug with the iphone web-app.

It would seem that the iPhone version of the Socialthing website is limited to the twitter character limit. IE: On the normal site, I'm only limited to 140 characters if Twitter is listed as one of the services I intend to post to. On the iPhone version of the site however, even if I only intend to post to something like Pownce, it shows a character limit of 140.
