Apple’s iOS mobile operating system adoption is growing, according to new metrics from  mobile marketing company Jumptap. The company reported today that as an operating system, iOS grew its market share from 26 percent in 2011 to 43 percent in 2012.

Here is more from Jumptap’s site:

Growth is likely attributed to the iPhone 4S and 5 launches in late 2011 and September 2012, respectively, as well as increased iPad use. Meanwhile, Android edged up slightly, maintaining the number one spot, while RIM declined significantly. For advertisers who seek reach, efficiency and results, targeting across both iOS and Android will optimize results.

The company also reported that tablet share doubled on the Jumptap network in 2012, as phone share dropped significantly. The company expects this trend to continue.
