Welcome to the latest installment of my weekly mobile summary.  To our loyal readers, I’m trying a little experiment and will be releasing the weekly wrap-ups on Mondays instead of Fridays as usual.  I personally like getting summaries on Monday mornings to set the tone for my week, so if you agree or if you don’t like the change, please leave a comment below.

The big story last week was the latest smartphone handset numbers released by Strategy Analaytics.  According to the report, 53 million smartphones were sold globally in Q4 2009 which represents a 30% increase from the year before.  Overall, 173.8 million smartphones were sold during 2009.  No surprise that Nokia topped the charts with 39% of the marketshare with RIM and Apple gaining marketshare to 19.8% (up 4.3%) and 14.1% (up 5.3%) respectively.

The other entertaining story was more Google vs. Apple cat fighting (you should expect it by now).  These two companies have turned the mobile market into a soap opera that includes name calling, product bashing and sometimes personal attacks.  Last week Google released their Google Voice webapp which circumvents iPhone’s “ban” on the Google Voice downloadable app.  And now this week, Google added Multitouch support to the Nexus One.  I’m not aware of any changes in Apple’s multitouch patent, so my best guess is that Google just decided to release the new feature to tell Apple “no more Mr. nice guy, we’re ready to rumble”.   Both companies seem to be mirroring each other with features (e.g. multitouch), acquisitions (e.g. mobile advertising – Google/AdMod and Apple/Quattro), and messaging (e.g. mobile is our future).  This should be an exciting week/month/year as these two companies battle without any playground rules.

As always, here is the mobile handset news I found from last week:
