Europe is awash with conference attendees this week - for TechEd Berlin and Øredev.
If you are attending either conference, you might want to download Conf to your iPhone or Windows Phone 7 (no Android for now, but coming...).
One warning for Øredev - the 'unusual' session starting times (eg. 10 after the hour) were not catered for in the code, so the "up next" algorithm doesn't really work. To be fixed in the next release!
If you're reading this, you must be interested in these conferences, so you probably want to know about these other mobile schedule apps too*:
