I've just been checking out the latest terms and conditions for the BT FON service... https://www.bt.com/wifi/secure/index.do
This is a joint initiative through BT and FON to turn all the BT Home Hubs into WiFi Hotspots. HOWEVER... if you read the small print, you are allowed to sign up to be a hotspot 'provider' even if you don't have a compatible router (so any one with BT broadband can sign up for free), and you will get your FREE inclusive minutes that can be used on any FON access point, OR BT OpenZone public wifi!
"Once opted-in you will also get access to the Internet when you are in a BT Openzone or in range of a FON access point outside of the UK. "
"Even if you dont have a hub you will still get the minutes of access when you opt-in. If you get a hub in the future and remain opted in it will automatically be configured to allow other BT FON Wi-Fi community members to log in"
The Free minutes you will get depend on your Broadband Option...
"Option 1 customers* get 250 minutes,
Option 2 customers get 350 minutes
Option 3 customers get unlimited** minutes of access per month."
So, if you are using a BT broadband connection you can now opt in for this regardless of whether you have the ability to share your connection or not and still benefit from the free minutes to connect yourself to hotspots!
