I have an iPhone 3GS and an iPad. I updated the iPhone to iOS 4.0 last week and all was well.
The app developers are updating their apps to run on iOS 4 and I am updating apps every day.
The iPad runs on iOS 3.2 and will not get an update until this fall.
Many of my apps run on both devices.
When you update an app, the older version of the app is tossed and all the devices must use the same version.
Some updated apps may cause issues if you are running them on an earlier iOS. This happened to me when I did not update to iOS3.1 but some of my apps did.
Yesterday, my iPad decided it needed 2 or more hours to backup. I did delete the previous backup and try again. It still took hours and now the backup is named “unknown” and dated for 2000.
I don’t have the patience or time to go through these long backups until the fall. And I don’t know which specific app may be causing the problem. I have a lot and several have been updated.
I have a plan or sorts. I am going to delete off the iPad all the non-specific iPad apps which I don’t “need.” Then I will try the sync again. If I have to, I will delete any apps that were updated yesterday. Luckily, the older versions were tossed in the trash and my OCD self did not empty it last night.
Hopefully this will solve the problem. But I wonder about people using older iPhones and iPod Touches which cannot be upgraded to iOS 4.0.
Weird. Even if you rename your photos in Lightroom and on export, iPad puts them in order of the original file name. Or maybe it is using capture time for sorting.
