Devicescape says its Agent now supports WISPr (Wireless Internet Service Provider Roaming), a new login protocol standardized by a subcommittee of the Wi-Fi Alliance aimed at enabling faster logins and roaming support. Some networks supported by the Agent -- including AT&T WiFi, FON, and T-Mobile -- will switch to WISPr logins as of Friday, Mar. 2, according to the Devicescape. Therefore, users are encouraged to upgrade as soon as possible, to ensure continuous service.
While I'm not entirely happy about giving my passwords to an external service, I tried Devicescape on my N800 and it worked as advertised: As soon as I connected to my home FON network it performed the web-based login, letting me use the internet without any manual intervention.
