Apple's iPhone is not as popular as it used to be in the UK, price-comparison service has claimed.

The company's Mobile Tracker, which ranks the popularity of handsets based on the number of sales of a device as well as the number of searches a device generates, puts the iPhone in sixth place in the UK.

The top three spots are taken by HTC handsets - the HTC Desire, the HTC Desire HD and the HTC Wildfire are first, second and third respectively. The BlackBerry Curve 8520 is fourth, with the Samsung Galaxy S fifth.

After the iPhone 4 comes the Motorola Defy, the Sony Ericsson S500i, the Samsung Galaxy G800 and the Samsung i600 rounds out the top ten handsets in the UK, according to the uSwitch Mobile Tracker.

Ernest Doku, technology expert at, said: "The competition is taking a huge bite out of Apple’s market. And, with over 800,000 deals currently giving away a smartphone for free, it’s easy to see how consumers are being lured away from the iPhone."

Though Android-based handsets, which account for half of the top 10, dominate, uSwitch recognises that all that will change when Apple announces the iPhone 5.

"Android phones have well and truly pipped Apple to the post. But, with just a couple of months until Apple is expected to give details of its next offering, it’s almost a dead cert that they will soon lead the way again in the race for smartphone dominance," Doku said.

It is also interesting to note that no Nokia handsets figure in the top 10.
