O2 will emulate AT&T in the US with the introduction of a business tariff for iPhone users this year.

Speaking to Pocket-Lint, an O2 spokesman confirmed the company: "Want to offer it as a service for business users looking to use the smartphone in their office".

O2 also spoke out against reports claiming the device has failed to meet expectations. Instead, the spokesman insisted, iPhone is the fastest-selling device the company offers.

The company also once again confirmed that 60 per cent of customers taking on an iPhone contract are new to the O2 network.
