Is iSync working with OS X Lion?

Mac OS X 10.4 / 10.5 / and 10.6 only > Mac 101: iSync

iSync has been discontinued in Mac OS X 10.7 Lion and is no longer included in the OS.

However, iSync v3.1.2 from Snow Leopard does work in Lion if you copy the application across.

It won't work forever though and is unsupported, as the SyncServices framework upon which iSync is built is deprecated in Lion, meaning it should no longer be used and will be completely removed in some future update.
