iPhone OS 4 requires newer version of iTunes.

April 8, 2010

UPDATE 2010.04.20:
If you have iPhone SDK 4 beta 2 installed, iTunes 9.1 will have no problem backing up the iPhone with OS 4.0 beta installed.

UPDATE 2010.04.10:
iTunes 9.1 definitely does not support iPhone OS 4.0 Folders. If you have folders in your iPhone home-screen, iTunes 9.1 will definitely fail to backup the iPhone. In one test, we’ve successfully performed backup and sync an iPhone 3GS (OS 4.0 Beta 1) with iTunes 9.1 where Folders were not present anywhere on the Home Screen.

According to reports, developers are having backup-problems with iPhone OS 4 and iTunes. iTunes 9.1 displayed a message “backup failed because it was refused by the iPhone.” It is apparent that a newer build of iTunes is required to fully interact with iPhone OS 4. Some Developers also reported that Folders on iPhone home screen were undone right after syncing with iTunes 9.1.

As Apple has done in the past, a special build of iTunes should be made available to developers.

    I am another victim of this (can’t upgrade itunes 9.0.3 to 9.1). I installed iPhone OS 4.0 beta using the newest SDK released today. Then I had to activate my phone on a windows PC using iTunes 9.1 because of the problems the mac version was giving me. Now I can’t restore my contacts or anything because they are on the Mac iTunes, and that one won’t upgrade! You really screwed me good this time, Apple!!!
