I came across this and it looks to be a pretty good deal for a new mobile that is likely to be worth £120 upward new (when I last checked on eBay buy it now)!
Unsure how good this company is at paying cashback though, but the tariff is also excellent for minutes and texts!
Don't forget cashback before taking out this deal.http://www.themobileoutlet.co.uk/handset.asp?txtMode=2&txtNetwork=3&txtHandset=377
