It seems the suresignal device would be useful for 2 reasons..

1/ if you really really need to boost phone signal level in your house

or

2/ 1 applies you don't know how (or your iphone refuses!) to connect your phone to your broadband..

All in all sounds like the latest marketing ploy (see latest adverts) from voda to increase market share and (cynically) get people to be routing data via their network rather than fixed broadband. Presumably the bandwidth drawn by the sure signal device does come off your monthly allowance from your provider?
