New iTunes Software Update Version 8.2.1Blocks Sync With Palm Pre Smartphone
If you have been used to syncing your Palm Pre smartphone with Apple iTunes so far and if you have upgraded iTunes to 8.2.1, you will find that your sync efforts have been breaking repeatedly. This is because Apple has now been blocking Palm Pre users from syncing iTunes with their handhelds.
The new iTunes 8.2.1 software update “provides a number of important bug fixes and addresses an issue with verification of Apple devices”. Quoting iTunes spokesperson, Natalie Kerris, “iTunes 8.2.1 is a free software update that provides a number of important bug fixes. It also disables devices falsely pretending to be iPods, including the Palm Pre. As we’ve said before, newer versions of Apple’s iTunes software may no longer provide syncing functionality with unsupported digital media players.”
Palm does not have a solution right away, so it is advisable for you to stay with iTunes 8.2 for the moment, if you need to sync your smartphone with iTunes. Otherwise, you could also use your USB to transfer files back and forth.
