The Apple iPhones share of the UK market has fallen from 30 percent to 18 percent over the past year, says Skinflint.co.uk.

Research by the price comparrison site revealed that iPhone now accounts for 18.3 percent of all smartphones sales in the UK, compared to 30 percent in July 2010. Furthermore, the cost of the highly-anticipated White iPhone 4 has dropped by as much as £102.01, thats 17 percent, since its launch in the UK in April.

The white version of Apple's smartphone was initially scheduled to launch in June 2010, alongside the black version. However, the white model was delayed, which Apple later revealed was due to lack of UV protection,  and subsequently didn't hit UK shelves until April this year. The SIM-free 32GB version of the iPhone in white was initially priced at £612 according to Skinflint.co.uk. However, it can now be picked up for less than £510 while prices for the SIM-free 16GB White iPhone 4 have been as low as £450.

Furthermore, the black version fell in price on the day the white iPhone 4 was released, by as much as £99.99.
