From your computer, download p12imprt.zip file from http://www.jacco2.dds.nl/networking/p12imprt.zip"P12imprt" consists of a Pocket PC 2003 executable (also runs on Windows Mobile 5.0) called p12imprt.exe and a few other files. They are distributed in a zip file. The zip file also contains a sample certificate file user.pfx. p12imprt.zip (version 0.2, size 320 KB, released 15-Mar-2006) - (PGP sig)
    2. Copy the p12imprt.exe executable to the device. You can use any method to do the transfer: ActiveSync, a flash memory card, Bluetooth, infrared etc. (The p12imprt.exe file is a Windows Mobile executable, not a Win32 executable. You cannot use it on your desktop Windows computer).
