Am still not ruling out getting one mind all that is putting me off getting one on contract is if p4u lock them too a specific network.
Vodafone handsets are normally unlocked and the branding is really minimal, its just a bootscreen with the Vodafone logo and 2 apps that don't seem to do much.
If it is locked, Vodafone can unlock it free. I don't know the situation with the other carriers.
