As of Friday 4th December, UK iPhone users who are using the Vodafone network will be offered a Carrier Settings Update when they plug their iPhone into iTunes. This update is for Vodafone UK contract Pay Monthly customers and not Pay As You Go customers. The carrier settings update you to Vodafone 5.1 (Settings, About, Carrier). One thing the update brings is that the word Vodafone fits perfectly next to the reception indicator without having to scroll. Internet Tethering is not supported. All this comes ahead of Vodafone UK officially selling the iPhone in Early 2010.
