A number of research firms have published reports on the sale of mobile handsets in 2007. While specific numbers vary a bit, IDC, ABI Research and Strategy Analytics all reported sales in excess of 1.1 billion handsets.
ABI Research reported 1.15 billion phones sold, marking a 15.6 percent increase over 2006. IDC reported sales of 1.14 billion handsets with a 12.4 percent increase over the previous year while Strategy Analytics indicated that 1.12 billion mobile phones had been sold.
Nokia remained on top (achieving a 40 percent marketshare according to IDC and Strategy Analytics) followed by Samsung, Motorola and Sony Ericsson. Motorola saw its marketshare drop significantly (about 38 percent over the previous year according to their own numbers) but expects to start to turn things around in 2008.
All three firms also revised their 2008 growth numbers down from previous estimates.
