Can one install the new operating system of the iphone 4s in the iphone 4?

By the way, does it have a new OS? ;)

The iPhone 4S comes with IOS 5 which you can install on your iPhone4 via software update through iTunes.
But you won't be able to use Siri (the speech assistant) since apple forbids it :-)

How do I check to see if the current apps will compatible with iOS upgrade?
Cloud Class® Course: Microsoft Azure 2017

Azure has a changed a lot since it was originally introduce by adding new services and features. Do you know everything you need to about Azure? This course will teach you about the Azure App Service, monitoring and application insights, DevOps, and Team Services.

This is something you can't do but usually all apps run on the newer versions of the os but won't automaticaly use the new features.
In case some Apps aren't running anymore (which hardly ever happens) developers usually provide updates withing a few days.
Apps which are created for IOS5 only won't run on older OS though...
So if you don't upgrade to iOS 5 sooner or later some newer apps won't run on your iPhone 4 with iOS 4.x anymore.
