The poll's results revealed that 25.3 per cent of smartphone users own an Apple iPhone, indicating a significant growth in the device's user base.
In a similar survey conducted by PC Advisor in April last year, only 17.2 per cent of smartphone owners said they used an Apple iPhone.
The main casualty of the iPhone's ruse in popularity appears to be Research In Motion's Blackberry device. In the previous poll, Blackberry was the preferred choice of 15 per cent of smartphone users. Now that figure has declined to just 9.7 per cent of smartphone owners.
Finnish mobile phone maker Nokia came second behind Apple, with 19.6 per cent of respondents saying they used one. HTC and Samsung came in third and fourth position, with 13.6 percent and 13.4 percent of votes, respectively.
