Quidco just e-mailed me with an offer from Three Mobile that seemed too good to be true: buy an iPhone 4S & get £115 cash back with the £35 per month tariff. Sadly, there is a catch. While the tariff itself isn’t too bad, with unlimited data, 2000 minutes and 5000 texts, the handset will set you back a minimum of £139. In essence, you will be paying £24 for the iPhone 4S, plus the cost of your monthly contract.
With a bit more digging around, I managed to find a much more appealing offer from T-Mobile, who are offering the 16GB iPhone 4S free from £45.56 per month, with £50 cash back. To take advantage of this offer, you’ll need to register with Quidco before you visit the T-Mobile website.
