The Apple iPhone 4 has dropped two places, to number eight, in the latest USwitch ranking compared to the previous one for the month of January 2011.
The first four places are still occupied by three HTC phones - the HTC Desire HD, the Wildfire and the Desire, followed by the Samsung Galaxy S with the fifth place welcoming a newcomer, the Nokia 1800.
The Blackberry Curve also fell down one notch while Motorola, with the Defy and the Flipout, manage to gain one place each. The only other Nokia phone in the listing was the C3 which fell down three spots.
There's no trace of either Sony Ericsson or LG, two of the other bigger mobile phone manufacturers on the market.
The data - which is compiled weekly - is derived from uSwitch Mobile as well as Omio's network of mobile comparison websites which feature some of the most frequently visited consumer technology websites in the UK.
It is interesting to note that all but one handset in the top 10 can be had from under £20 per week and all top four phones are Android-based. The cheapest you can get the iPhone 4 is on a £45 per month tariff on a two year contract.
There are at least three reasons which might explain the fall of the iPhone 4; the arrival of new, cheaper Android-based handsets like the Galaxy S or the HTC Desire HD, the arrival in less than four months of iPhone 5 and the current economic climate.
