From what I have seen and read I am lead to beleive the N900 does not support javascript, is this correct?

Im in the UK and have been trying to connect to a BT Openzone hotspot using WiFi. It fails to load the next page after I select Vodafone from a list of partners. It seems to be calling a javascript probe of the device which fails and then the browser comes back with "MicroB cant establish a connection". Also the same occurs with firefox stating "Firefox can't establish a connection to the server at wlan.vodafone.net...etc"

Wondering if any UK users have seen this?
