Back in January, we finally saw Gingerbread fall below 50 percent in Google’s Android distribution numbers for December. At the same time, Ice Cream Sandwich and Jelly Bean both saw increases. Now only one Android version is seeing continued growth.

In the latest Android distribution numbers, Jelly Bean has grown 3.4 percent to a total of 13.6 percent of the entire Android market. The increase can be attributed to any number of things including the Galaxy S III finally being upgraded to the latest version of Android. Sales of Google’s Nexus 7 and Nexus 10 tablets likely contributed to the increase as well.

What about the other versions? Surprisingly, Ice Cream Sandwich is down, but only by .1 percent. Android 4.0 ended January with 29 percent of the market compared to its 29.1 percent from last month. This is probably an anomaly as ICS will most likely continue to grow as those with cheap Gingerbread handsets will upgrade to now cheap ICS handsets throughout the year.

Speaking of Gingerbread, the Android OS that won’t die is still falling slowly as it only lost a few percentage points over the month. Android 2.3 now holds 45.6 of the Android market. It will only continue to decline as more users upgrade to devices with Android 4.0 or 4.1/4.2.

It will be interesting to see how the Android market continues to evolve over the course of the year. I have a gut feeling that Gingerbread’s days are numbered, and that its overall distribution will see a huge decline sometime in the middle of the year. Google’s expected rollout of Key Lime Pie (or Kandy Kane) may also have an impact on overall distribution numbers later this year.
