I've (again) changed schedule of what to implement and I've spend fourth Hackweek 6 day by doing more cleanup and documentation work than real coding.
The major new feature is support for direct installation of the applet to the phone, so the installation is now easier. There were minor improvements on the both sides to allow support for calls and deleting of SMS messages. Adding calendar and todo entries is still left for future (hopefully tomorrow).
Rest of the time was spent collecting feedback from users testing the code (surprisingly there are already few brave users who gave it a try). It resulted in few bug fixes and improved documentation.
