I was able to attend a professional development webinar, from my iPhone4s, without any trouble at all. As a new mom caring for an active 7-month old, it was important that I be able to bring the webinar with me (as I changed diapers, breastfed, etc) and I was able to do this, easily and effectively. I highly recommend this app and look forward to more webinars in the future.
