I was at the Residence Inn in downtown Toronto this weekend (I hate to see my Roger's roaming bill...I'm on TMO USA normally). Anyhow, I was able to connect to their wifi and surf, but no UMA. UMA works fine on my home wifi. So is that another aspect we should track here? That is, wifi connect versus wifi connect+UMA working? Not sure what would cause UMA to work or not work on a public hotspot. Does it need to have ports open or something?
