iTunes 10.4.1 won't sync iPad 1
I have a jailbroken iPad 1 running ios 4.3.2 that has synced with iTunes 10.4.1 without any problems for many months.
Suddenly, iTunes 10.4.1 will no longer sync my iPad. I can transfer files (books and apps) to the iPad via DiskAid and FileBrowser, and the iPad otherwise functions well, as it always has, but I cannot sync with iTunes.
When the iPad is connected to my MacBook running os 10.6.8
iTunes recognizes it and displays all of its contents, but will not sync or transfer new files.
I get no error messages and my jailbroken iPhone 3 running ios 4.2.1 syncs without a problem.
Any ideas why iTunes would suddenly stop syncing?
