Vodafone has moved in to mock UK operator O2 after it commissioned a survey that found Vodafone the better operator.

“This week’s independent study by O2 is a welcome endorsement of Vodafone having the best network in the UK. We’re seeing continued high demand for our range of smartphones, including the iPhone, driven by customers enjoying a great experience from our outstanding network”, says Guy Laurence, CEO Vodafone UK

Earlier in the week O2 commissioned an independent network speed test by SIRODA, however while winning out against T-Mobile, Vodafone, Orange and 3 when it came to downloading music on the go, the operator lost to Vodafone when it came to general surfing the Web.

The move by Vodafone is only likely to enrage O2 as the two battle it out to prove who is the best operator for the latest smartphones.
