Content aggregators complained that they needed the mobile user agent header to present mobile specific content. This was not passed to them when the customer went through the WTE.

As a short-term tactical fix, Vodafone introduced a whitelist for made-for-mobile sites.The WTE does not render sites on the list and passes the user agent. Requests to be added to the whitelist should be sent to mobileinternet.whitelist@vodafone.co.uk
