"untitled" device. When I get the set up your phone
screen I cannot get it to restore from backup it
just says "Rons iphone" but when I click on it =nothing
happens.Any help appreciated.

p.s. yes I did a backup before upgrading.

You will need to do a restore once again. Once the restore is successful, then do a restore from backup of your data. In the worst case, set it up as a new phone. It will sync everything again.

Why must I do another restore?
It works(iphone) fine.
Just cannot sync.
What is "sync" looking for?
Why under device does it show "untitled" ?
under setup your iphone there are two options
setup as new or restore from my prev backup
I cannot do either cause it won't sync.
please somebody help

what version of iTunes you are using?
I suggest you should upgrade iTunes to the latest version if you are not using it

After I upgraded to 2.0, my iTunes was not able to identify the phone but it did tell me that I have to upgrade it to be identified.
