Android and iPhone Update History

Android Fragmentation:
10 of 18 were at least two major versions behind well within their two year contract period.
11 of 18 stopped getting any support updates less than a year after release.
13 of 18 stopped getting any support updates before they even stopped selling the device or very shortly thereafter.
15 of 18 don’t run Gingerbread, which shipped in December 2010.
In a few weeks, when Ice Cream Sandwich comes out, every device on here will be another major version behind.
At least 16 of 18 will almost certainly never get Ice Cream Sandwich.
“It only gets worse for people who bought their phone late in its sales period.”
