Last Tuesday, Apple pushed firmware 3.1.3 bringing us minor updates, but upgrading the baseband. Mobile ad group Medialets reports that in the last 6 days, only 14% of the iPhone users updated to 3.1.3. The company also noted that it saw a 13 percent drop in installs of 3.1.2, meaning 87 percent of the upgrades to iPhone OS 3.1.3 came from users who were already running the latest version of the mobile operating system.
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.
Yesterday, the iPhone DevTeam released PwnageTool 3.1.5 , allowing users to create custom 3.1.3 firmwares which will not update the baseband , therefore they can jailbreak and unlock their iPhones. Given the fact that back in Oct. there were around 38% jailbroken iPhone in circulations, we’ll see if the percentage of people that update to 3.1.3 will grow, or people will just wait for the next major release.
