I had to buy this in order to get a handset, but I don't have any use for it.
Vodafone sim card with £10.86 (I bought £10, not sure where the 86p came from but it's there!!) on http://www.phones4u.co.uk/networks/network_tariff_viewer.asp?TariffKey=1304
Vodafone Smartplus .
Will sell for no less than £8 delivered (would rather use it myself than give it away!!) or will consider trade for nintedo DS game.
