Problem provisioning iPhone with 3.0.1 after it worked before

Question

After I installed iPhone OS 3.0.1 on my iPhone I followed the instructions on Apple's website (see this question), created the symbolic links, and everything worked fine. That is, I could test my application on the iPhone.

Now it stopped working. I verified that the symbolic link is still there. I also tried deleting and recreating it and I also tried naming it 3.0.1 (7A400) instead of just 3.0.1. None of this worked, my iPhone is still showing up as "Could not support development" in the Xcode organizer.

Here are the contents of /Developer/Platforms/iPhoneOS.platform/Device Support on my computer:

Macintosh:~ thm$ ls -la /Developer/Platforms/iPhoneOS.platform/DeviceSupport/

lrwxr-xr-x   1 root  admin   12 13 Aug 22:42 3.0.1 -> 3.0 (7A341)/

I wonder if this is caused by my recent upgrade to Mac OS 10.5.8? I'm not sure whether I tested anything on the iPhone after the upgrade.

Did anybody else have a similar problem? Any ideas what might be causing this?

Any help is greatly appreciated.

Answer 1

Try starting with the simple stuff. First, have you tried restarting xcode, your Mac, and the iPhone?

Answer 2

Have you try this? Work for me.
