Needing help with iphone

[ohsobad_chevy]

I am on ios 5 beta, running 10.5 beta 4 itunes. Win XP

I was typing a text when all the sudden the activation screen appeared. I connected to itunes to see what is going on. I get an error message "The software on the iphone has expired and must be updated to a newer version." I click ok and nothing happens.

I then tried to restore and I get: There was a problem downloading the software for the iphone, the requested resource was not found."

Also, I know I have backed up before and I do not have an option to back up from restore when I right click my phone.

I do shift-restore and point it to my ios 5 and it will go through the process and then back to the activation screen where it will not do anything. I go through all activation and it restarts with another activation screen.

Someone please help ASAP.

The beta 1 of the iOS 5 expired. You have to put the device into recovery mode and upgrade to 4.0 beta 4.
