Hi People, I finally found an update to enable me to sync my SE P1i with iSync on my MBPro running Leopard. Took me about 3 tries after I installed the update, and I think on the last attempt I had to untick the iCal sync option for it to finally work. My main concern is to sync my over 1,300 contacts, and I finally was able to do it. here's the link to the update file: http://www.jonathansblog.net/sony_ericsson_p1i_isync_plugin_apple_computers_mac_os_x Hope it works out for you. Have a good one.
