Looking for a new phone and wanted to get the HTC Hero but a little bit too much for me per month. So rang Vodafone and talked to them about the new HTC Tattoo. Anyways, to cut a long story short, managed to negotiate them down from £25 a month for 300 mins, UNLIMITED TEXTS and UNLIMITED EMAIL/WEB to £17.50 for 18 months.
Hope this helps others who want to try this phone out.
Oh, the phone is free.
