As 2009 is reaching its end, the Nielsen Company, a market research firm has announced Apple iPhone as the most popular mobile phone this year. Blackberry and LG mobiles are also doing well, according to the latest data released by Nielsen.

The result illustrates the iPhone success – its performance is all the more impressive since the device is available on only single carrier – AT&T. The result however does not include any Android powered devices, Google’s open source mobile operating system, such as Motorola’s Droid, available on Verizon Wireless which was released this fall.

It is believe that next year, Android devices will sit on the top 10 mobile phones in US. For 2009, Apple 3G iPhone grabbed the number one spot with a 4% “embedded base of all subscribers,” a measure of market share. The BlackBerry 8300 Series, which includes the Curve, 8310, 8320, 8330, and 8350i models, came in second with 3.7% percent, while the Motorola RAZR V3 series, which includes the V3, V3c, V3m, V3i, V3i DG, came in third with 2.3%.

LG locked up the fourth and fifth slots with its LG VX9100 (2.1%) and LG Voyager (1.7%). Blackberry and LG models claimed four of the remaining five slots to close out the top 10.

Meanwhile, Google, Yahoo and YouTube were the most visited sites accessed via mobile devices in 2009. Google’s search engine led all websites accessed by mobile phones, while Yahoo Mail came in second, followed by Gmail, the Weather Channel’s website, Facebook, MSN Hotmail, Google Maps, ESPN, AOL Email (run by DailyFinance’s parent), and CNN News.
