It is painfully obvious to me (unless I'm doing something wrong?) that it isn't possible to downgrade to 3.1.3 once you have a version of iOS4 on your device. So my question is, did I complete screw myself out of my apple care when I put the GM on my phone? Is there ANY WAY I can put the release version on my phone?
All these problems! I was thinking about upgrading to the final version, but I think I'll just stick with the GM for now......luckily, my phone works great with it.
