iso 10 upgrade
I have an ipad 3.3 whose iso is 9.3.6, is it possible to be upgraded to iso 10?
iPad2, iPad3 or original iPad mini cannot be updated beyond iOS 9.3.5 (WiFi Only models) or iOS 9.3.6 (WiFi & Cellular).
Apple ended update support for these devices in September 2016. None of these models can be updated to iOS 10 or later versions, as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS. The 32-bit platform upon which they are based is effectively obsolete, more recent versions of iOS being designed for 64-bit hardware which your iPad does not have.
Many App Developers have also dropped support for older devices and iOS versions preceding iOS11/12/13 - and have withdrawn older versions of their Apps from the Apple App Store, now limiting utility and usefulness of older devices.
If Apps that you need to use now have higher minimum iOS-version requirements, your only option is to replace your iPad with newer model. Even the basic current iPad7 model supports current iPadOS 13.x - and has hardware specifications that will vastly outperform your old iPad
I hope this information is helpful - if only in clearly stating the limitations of your iPad3 and your potential options.
