Cell Phones, PIMs and Linux?

graner asks: "I've just got one of those nifty Motorola StarTac (model ST7800W) phones. Has anyone every tried to enter in a bunch of phone numbers? It sucks. With the optional data cable you get a CD that has some software from StartFish called TrueSync that only works on Windows boxen, but it does allow you to "sync" the phone with several different apps (outlook, etc.). Does anything exist that will allow you to do this under Linux? I've been all over the net and found a lib that lets you work with a GSM phone, but from all I can tell it won't work with this type of phone. I'm not opposed to firing up a serial sniffer and start hacking, but I hate to reinvent the wheel. Does anyone have any info/pointers/links or anything that resembles useful info? "
