I was trying one of the example urls to look at the info of a page, except that I wanted to see the output format in xml instead of json:

http://api.bit.ly/info?version=2.0.1&hash=31IqMl,3j4ir4&login=bitlyapidemo&apiKey=R_0da49e0a9118ff35f52f629d2d71bf07&format=xml

Firefox complained that the xml wasn't well formed because it had an un-escaped '&' when it should have used a & instead.

This appears to have been resolved. Jacob, are you still having problems re: this issue?

Thank you. I have verified that the problem is resolved.
