We only provide the latest SDK on our site. I've run several of the 4.2.3 samples on the iPhone 4. You can try it out and see if 4.2.3 meets your needs on that device.

Is it possible and reasonable to download older versions of Vuforia SDK which can work on iPhone4?

The iPhone 4 has been reported to run some of the 4.2.3 sample apps, but it is not officially supported. The minimum iPhone supported and tested with Vuforia 4.x is the 4S.

They have run fine in our tests :)

Runs fine on iPad 3   Have not tried iPhone 5 yet..     or iPad Mini

Basically it will not use the advanced instruction set on the iPhone5, but in reality it is still fast enough.

Also, other engines like Unity are not yet supporting armv7s but most likely will eventually.

So nothing to worry really.

Good call! Thanks, Nalin! Should have caught that one myself...

So, do you know what the implications are if arm7s is not supported?

I think from memory it might need a launch image for the full size of iPhone5 screen in order to trigger non letterbox format.

Thanks Nalin. I did try that earlier yesterday, and although that let's you build, it displays the black bars on the iPhone 5. What am I missing?

BTW we are officially supporting the iPad 3 and iPhone 5 - we need to update our docs.

Hi Jack

The library does not need to be updated.

In Xcode go to Valid Architectures in Build Settings where it says:

    armv7 armv7s

...and change it to 

    armv7

Build and Run :) 

In answer to your last point, Unity does not yet support Armv7s officially.  If you use the latest Unity you will get an option to compile for Armv7 and if you use this it should compile and run fine through XCode.

Well, I managed to build a sample project to an iPad3, so that doesn't seem to be a problem.

As for the iPhone 5, I get this error:

(null): File is universal (2 slices) but does not contain a(n) armv7s slice: ../../build/lib/arm/libQCAR.a for architecture armv7s

Is there an updated version of libQCAR.a that I can install such that iPhone 5 would be supported? I mean, it is supported if you use the Unity extension, so there must be something I'm missing.
