Well I got one on the phones4u vodafone 12 month deal. Love the phone and everything is fine so far. Used Top cashback, which was tracking the cashback within a day or two.
Interestingly I downloaded the "my vodafone" app today. My texts show as unlimited and I have unlimited data for 3 months of data test drive. The deal was 300 mins, 3000 texts and 500mb of data.
3000 texts is vodafones definition of unlimited texts.
