One of the most popular (if not the most popular) freeware application for Windows Mobile, S2U2 (Slide to Unlock) has been recently updated to version 2.22, bringing new features, fixes and compatibility with HTC Touch Pro, Touch Pro2 and HD2.

Here’s the changelog (quote):

- added option to lock/unlock when open/close the Keyboard on some devices (e.g. HTC Pro/Pro2). (S2U2 Settings -> Others)

- fixed an occasional battery drain on some devices.

- fixed the Answer key was not locked on HTC HD2 even when “slide to answer” was active.

- fixed an occasional issue that S2P was invoked during BT file transfer.

- a few minor bugs fixed.
