Want free T-Mobile wifi service? Well, you’ll either have to run Microsoft IE 7 with Windows Vista or you can access it with a Agent changer hack for Mozilla Firefox. As part of the T-Mobile, Microsoft partnership, they are allowing Vista users to get 3 free months to T-Mobile Wifi service which expires in April, 30th 2007. If you go and purchase this wifi plan alone, it will cost you $39.99 a month. This is a real deal right here!

Here’s how to use the service without Microsoft or Vista:

1. Download Mozilla Firefox here.
2. Download the Agent Switcher plugin.
3. Add the following values:
   1. Description: Internet Explorer 7 (Windows Vista)
   2. User Agent: Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)
   3. App Name: Microsoft Internet Explorer
   4. App Version: 4.0 (compatible; MSIE 7.0; Windows NT 6.0)
   5. Platform: Win32
4. Signup for T-Mobile wifi here!

After you register, you will be able to surf the net at all nationwide T-Mobile wifi locations!

**UPDATE**

Mozilla Firefox hack does not work, an ActiveX required to install on IE 7. Sorry.
