Kantar Worldpanel’s December smartphone market share numbers are out. And they are as fascinating as ever. Kantar pegs the BlackBerry market share in America as 1.1% last month, down from 1.4% in November. Surprisingly, Windows Phone’s market share also ticked down to 2.6% in December from 2.7% in November. That might be a statistical artifact, but it is surprising not to see a substantial boost in Windows share considering the marketing support and new devices from AT&T (T).

In Europe, Windows Phone is rapidly picking up steam. Its market share soared to 13.9% in Italy from 11.8% in November. In the UK, Windows Phone’s share moved to 5.9% from 5.1% in a month.The EU average share of Windows Phone bloomed to 5.4% from 4.7% between November and December.

At the same time, BlackBerry dipped to 4.0% from 4.4%. The stage is set for the spring battle between Windows Phone and BlackBerry camps.

Interestingly, Apple’s (AAPL) share in the UK slipped to 32.4% in December from 36.1% in November. The massive popularity of Samsung (005930) models in the British market was undoubtedly the main reason; Android’s share hit 54.4% in the UK.

This is the latest sign that Apple’s market share problems outside the U.S. market are not limited to emerging markets and Southern Europe. The UK has traditionally been the second most loyal market to the Apple brand, right after the United States. According to Kantar, Apple slipped 2.1 percentage points in America between November and December, ending up with 51.2% share of the smartphone market.
