ajobbins: Don't see an issue. Especially at it's cheap (obviously subsidised), clearly labelled as locked and unlockable for a pretty low fee.
This differ from days of old where Vodafone used to lock handsets sold on long term contracts and they either couldn't be unlocked for a period of time, or doing so was prohibitively expensive (despite some pretty pathetic subsidies on the handsets).
Wonder what the margins are on handsets.
