CNET Asia is reporting that HTC confirmed it will launch the HTC Sync Manager desktop application next month, which be able to access an iPhone's backup files, extract its data and import it into an HTC One. The idea is to let those switching from an iPhone to an HTC One easily transfer photos, videos, calendar entries and text messages.
As CNET points out, the text message feature is key, because there's currently no easy way to transfer archived text messages between devices.
Your guess is as good as anyone's as to how long this upcoming HTC Sync Manager will be allowed to work, as it's perfectly reasonable to assume Apple will try to find a way to block it, much like they blocked the Palm Pre from syncing with iTunes. The company also went back and forth with several MP3 player manufacturers back when the iPod was young.
