There has been some confusion over the iPad 2 iOS 9.3 update, because there is a second separate Activation bug affecting many older devices, including the iPad Air and earlier and the iPhone 5s and earlier.
While the iPad 2 iOS 9.3 update fixes the first Activation issue, it does **t address the second Activation bug that affects many more devices. Apple has **t resumed signing iOS 9.3 for older devices, so many customers who have an iPad Air or earlier, iPad mini 2 or earlier, or iPhone 5s or earlier are **t able to download and install iOS 9.3 if they have **t done so already.
Apple has said it is working on a fix for the second Activation issue, which will be released in the form of a new update to iOS 9.3 in the next few days. Until that time, customers who have an older device will need to remain on iOS 9.2.1.
