Get ready to rumble, the latest Gartner and IDC smartphone numbers are out to give us a pretty good idea of how things shape up globally. Remember, IDC measures vendor shipments while Gartner measures actual handset sales to end users. So what does the data tell us? Well, to start with, in terms of smartphone devices, Gartner claims a 48.7% increase in smartphone sales of 54.3 million units in Q1 2010 compared to Q1 2009 -- IDC pegs growth at 56.7% on 54.7 million units for the same period. Both estimates easily outpace the 17% or 21.7% growth in worldwide units of mobile phones moved according to Gartner and IDC, respectively.

IDC's list of top 5 smartphone device makers (pictured after the break) has Nokia at the number one spot repeating its 39.3% share as it did in Q1 of 2009 while RIM is down slightly from 20.9% in 2009 to a 19.4% market share in 2010. Apple (up from 10.9% to 16.1%) more than doubled its device shipments in the last year as HTC (up from 4.3% to 4.8%) and Motorola (up from 3.4% to 4.2%) all managed to increase their shares on higher volumes.

Regarding smartphone OS market share, Android's global numbers echo its success in the US jumping from a 1.6% market share to 9.6% in just one year. Gartner claims that sales of Android-based phones increased 707% year-on-year to displace Windows Mobile in the top 5 for the first time. Apple's iPhone OS also saw growth from 10.5% in 1Q09 to 15.4% in 1Q10 as both RIM (down from 20.1% to 19.4%) and Symbian (down from 48.8% to 44.3%) dropped.
