Google promised to improve the software release fragmentation on Android, but these numbers do not indicate progress but rather some pretty significant regression.
That's why Google's new partner Intel just released a new smartphone (RAZRi) saddled with Android 4.0 ICS, which is already a year old, despite having based the "new" model on an existing design, and having coordinated with Google's own Motorola subsidiary to bring it to market.
Similarly, Nokia's latest announcement of its new WP8 Lumia lineup was hamstrung by delays related to Microsoft's new software release.
Samsung's flagship Galaxy S III is just now getting the latest Android 4.1 Jelly Bean release in some countries, despite it being released months ago.
The situation for Android doesn't appear to be getting better.
i OS 4 was particularly notorious for heaping too much on the plate of previous devices, resulting in many users complaining that they were better off not upgrading.
