Device failed to become ready - Ipad

Ok, so I have been building versions for the ipad, and it's been working fine. (This is in xCode) Except today. I updated my ipad to 3.2.1, so I assume that's the problem, what else can it be..

Has anyone else had problems with this, and found a solution?

Again, the error is "Device failed to become ready, try rebooting the device)

Any hints would be great, I updated the iphone sdk, but that did not help..

Thanks a lot.

Ok, I found out the problem :)

So, after installing 3.2.1 on the ipad, I had to install the new sdk.

Then, I had open the organizer in xcode, and re enable the ipad for development. :) phew, so then it worked. :)
