Can't install app on Device 3.1.2
<p>I can install my app with the profile in my IOS4.0 device, but the same profile can't used to install on IOS 3.1.2 device.
My Xcode is SDK 3.2.3+IOS4(SDK 4).</p>

<p>BTW, i set my "Base SDK" = iPhone Device 4.0, "IPhone OS Deployment Target" is "iPhone OS 3.1.2".
The error info is "A valid provisioning profile for this executable was not found."</p>

<p>Thanks a lot.</p>
