14% of iPhone users installed v3.1.3 last week
by David Barkoe
We’ve crunched the adoption numbers for last week’s release of iPhone OS v3.1.3 and found that among the developers’ apps we track 14% of their users installed v3.1.3 between 2/1 and 2/6, with adoption growing steadily each day.
We also saw a drop of 13% in installs v3.1.2, meaning 87% of the upgrades to v3.1.3 came from users that already had v3.1.2.
The other interesting data point is that roughly 13% of these users are slow to upgrade their iPhone OS and are using a version prior to 3.1.2.
