First of all, i have iphone 3gs, ipad1 and ipad2 authorised with my win7 PC (64 bits) and one ipad1 and itouch 1st authorised with an iMac, iphone 4 and itouch 2nd with a xp netbook.
Installing ios5 went very fine with the iphone 4 and xp in the same day when ios5 released.
But with the iphone 3gs, ipad1 and ipad2; i had no luck up to now.
The main problem is, after i have upgraded to itunes 10.5 and when i click the edit>preferences, itunes freezes. After approximately 5 minutes, the preferences window opens. I can navigate all the preferences smoothly except for the devices tab. When i click it, it again freezes for 10 mins, after that i see an empty backup list. I know that my backups are in my HDD (i check the backups at its location).
Also when i tried to make a new backup, an error window says something like it can not communicate. When i try to make the communication tests, it passes.
I' ve searched the net and found those :
I' ve done anything in those articles and with non of them i could succeed.
I' ve uninstalled itunes and components in the order the article describes. Deleted configuration files, checked anything that remains. Opened a new account. Disabled all non ms services and programs. Deleted all my podcasts, changed them to update manually. Anything that is written in those articles for several times and came to a conclusion that i think the problem is with this version of itunes.
The worst thing is not only being able to use woderful ios5, my ipad2 64 gb + 3g' s microphone has a failure. I will change it at the service. But as soon as i can' t make a backup and update to ios5; i cannot.
So, i' am really very sad about this and i please from Apple and all the community to find a solution and/or Apple, please find the bug and release an itunes update with a fix soon.
Apple, i can send you any file that you can request from me to speed up the process.
And community please, don' t write anything without reading the links i have written above!!!
