How to downgrade to ios 4.0

Hello guys,

When I first got my iphone I upgrade it to 4.1 but when yesterday I signed up for the Apple developer program, paying $99, so I could be able to install my app in my iphone.
Funny thing is that the SDK doesnt support this version of the IOS so I can't still do it. The Organizer of XCode shows a link to downgrade it but it doesnt work.
Do you know if there's an official way to do that? I tried irecover but it blocked my iphone for some hours.

Thanks.

I would update both, the iPhone SDK and your iPhone to iOS 4.2, so everything should work perfectly without any troubles... I think the problem is your SDK if you haven't upgraded it to 4.2...

Hope it will work..

Thanks, I did and now it shows this error.
"the identity iphone developer doesn't match any valid certificate apple"
You know how to fix it?

That should be easy to fix... ;-)

You need to login to the dev center and go to the iOS Provisioning Portal (link on the right side)

There you need to create your Developer Certificates and download them... But this is a bit tricky.. Google for iPhone Developer Certificates or something like this and you'll find lots of great tutorials...

You need also to connect your device to iTunesconnect... You can do this right in the organizer or in the provisioning portal.

Good Luck!
