I recently switched to Verizon because TMobile had horrific reception where I now live.
I got the LG VX5400 cause they were on sale, have good battery life and had bluetooth which as it turns out works with OSX.
On Tiger, I have enabled bluetooth on the phone and mac, paired the devices and can send address book entries to the phone.
iSync does not work.
This is just for google as I couldn’t find any info on this at all when looking.
Update: I have since noticed that while I am able to transfer one contact at a time using bluetooth, if I select multiple contacts and transfer them as a group only the first is actually transferred.
