iPhone Ad Hoc Distribution Build does not work on 3.x Devices

Question

We have made many Distribution Builds, so we are familiar with the daunting iPhone provisioning process.

We have entered all the devices into the Provision Portal, we have downloaded all certificates, and when we distribute our BETA build, it is only working for users on iOS 4.x. This is strange behavior because it wasn't doing this before.

Our iOS Deployment Target is set to: iOS 3.0

Base SDK is: iOS Device 4.1

Don't you think if we had a reference to a Base 4 SDK method, that it would at least install, but then crash? We are getting the infamous:

"The executable was signed with invalid entitlements"

This seems like an odd error when other all other devices that are on iOS 4 are working and all the iOS 3 devices are getting this?

We are stumped, thanks!

Answer 1

Are you doing a build and archive? You might want to try building it and manually zipping it along with the provision and sending that to your beta testers. I had this same problem with iOS 3 devices and zipping it manually seemed to work.

Answer 2

Versions of iOS prior to 3.2 cannot take advantage of an embedded provision file (included in the zip). For those devices, you have to install the .mobileprovision file separately by dragging it into the library in iTunes.
