After using FOGBUGZ and JIRA for agile, i have decided that neither tool is really ideal to support the model. Can you get either to work. Yes. JIRA is actually a little better because of the ability to customize more (Create user stories, etc) But if you really want your team in SCRUM mode, you need to have everyone looking at a burndown chart and everyone looking at a backlog and i think you should look at tools like SCRUMWORKS. The basic version is free and it will give you what you want. Use JIRA and Fogbugz for what they were meant to do, keep track of bugs and requests but not be a full SCRUM management tool.'
Update: You can use Greenhopper plugin to JIRA which is a little better to support agile projects.
