Republishing?
Hang on a minute....
Vodafone are downloading web pages to their servers, messing them about and then (maybe) adding advertising to them...
...and then REPUBLISHING them to the handset user.
Errr.... isn't their a copyright issue here? Most web sites (pretty much all the commercial ones, and a lot of non-commercial ones) specifically disallow republishing of their material unless you have their express permission.
