Entertainment & technology retailer HMV is to stock a limited edition Teenage Cancer Trust-branded iPhone 4/4S cover with the aim of raising funds and awareness for its nominated charity partner.

The soft touch case, which is manufactured by HMV's technology accessories supplier, Griffin Technology, will be sold in HMV's 220 UK stores nationwide and online at hmv.com.

The product will officially go on sale from this Friday 20th July and will retail for the bargain price of just £7.99 – around half the cost of a standard iPhone cover of that quality and therefore excellent value.

£1.70 from each sale, potentially over £40,000 in total if all the cases sell through, will go to Teenage Cancer Trust to help fund their units that are located closest to HMV stores. Such an amount, if achieved, would help push the overall total raised by HMV for the charity over the past 18 months towards the £200,000 mark.

Siobhan Dunn, Director of Fundraising at Teenage Cancer Trust, said: “These iPhone covers are a great way of raising vital funds for young people with cancer. Teenage Cancer Trust is the only UK charity dedicated to improving the quality of life and chances of survival of the six teenagers and young adults diagnosed every day. So if you have an iPhone 4/4S, head to HMV and grab one of these cool covers to help more young people fight cancer.”

HMV's Technology Buyer, Dean Millward, who developed the product with tech partner Griffin Technologies, added: "The huge growth in the smartphone market has been matched by similar demand for the protective soft touch cases that users often put on them.  Increasingly these are also taking on a strong fashion and design element, and our stores now carry over twenty different styles for the iPhone 4/4S alone. At such a great price I really hope this limited edition version for Teenage Cancer Trust sells out quickly and also helps to raise awareness for the wonderful work the organisation does."
