3 Sells Cheapest Apple iPhone 4S In UK With £115 Cashback Offer

3 has teamed up with Quidco to give a whopping £115 cashback to anyone that uses the cashback site to grab an iPhone 4S handset on the One Plan. Note that the offer - available here - expires on Monday and requires that you register on Quidco, a membership that will cost you £5 annually.

The deal includes 2000 minutes anytime, any network, unlimited data with unlimited tethering, free skype calls, 5000 texts, 5000 three-to-three calls, free voicemail and the phone with an upfront fee of £99 and a monthly fee of £35 per month.

This means that once the cashback is accounted for, the total monthly outlay excluding the upfront cost is £34.33 per month. The phone was officially launched today with many expecting more than four million iPhone 4S phones to be sold by Monday.

The phone is externally similar to the old iPhone 4; the main differences being inside; there's a dual core SoC, the A5, with an eight megapixel camera, Siri, a slightly better battery life and that's it really. The front facing camera, the RAM, the screen and the rest of the specs are the same.

You can still enroll in our competition to win an iPhone 4S by answering a very simple question before the 21st of October. Terms and conditions as well as the other details are here.
