Installation is very simple:
Download the attached skin-sx1.zip file
make a backup of the epoc.ini and epoc.bmp files that should be present in %EPOCROOT%\Epoc32\Data
Unzip the content of the zip file into this directory
Here it is.... you can now develop application for the Siemens SX1 device!

As you may search for it, note that the power on key is located on the battery icon (!).
Hi,
It is working fine for me. Only thing you have to change the floowing lines in epoc.ini files according to your drive.
_EPOC_DRIVE_D c:\symbian\6.1\Series60\epoc32\wins\d
_EPOC_MMC_DRIVE E:
_EPOC_ACTIVE_MMC 0
