Hi, Before I go continue- I have an ADC subscription, and have had one for quite a while. I'm trying to install 4.2 B1 to my testing device (iPhone 4), however, iTunes is giving me error 10 when trying to install 4.2 to the testing device. I am running iTunes 10.0.0.86 on Windows, and on the Mac - I've tried both - the same result. I'm not seeing an iTunes beta in ADC iOS dev site. So, what could I be doing wrong?
