Free USIW Wi-Fi hotspots are supposed to be available around the City now (total of 117). I’ve attached the map for south Minneapolis.
I tried one in Standish Neighborhood this morning with my iPod Touch and could not find a way to access the system and create an account. You do have to have a credit card for creating the account although you won’t be charged. (I really wish they could have figured out a way to do this for people that don’t have credit cards.)
