Eltima Software has released SyncMate 3.5 (http://mac.eltima.com/), a new version of their US$39.95 sync tool for Mac OS X. The main option introduced in the new version is compatibility with iOS 5 and Android 4.x devices.
SyncMate 3.5 will sync iCal, Address book, iTunes, iPhoto, folders, bookmarks, notes, and other data between iOS devices and a Mac. Version 3.5 also features non-sync options. For example, you can mount Android devices as Mac disks, manage SMS messages on Mac, export SMS messages to different formats, etc.
