I recently downloaded and installed iOS5 beta 2 on my iphone 4. The problem I am having is when I try to sync, the option is grayed out and unavailable, both under the summary tab in itunes as well as the apps tab. Unfortunately, because of this, i had to go back to beta 1 and hoping for some answers on why this is happening. My brother had no brother doing it. BTW all my contacts, texts, and photos are on my phone, its just a problem with my apps.
