Downloading Blackberry 7100t Contacts into Prius

I've talked to RIM and there is no support for anything other than the Bluetooth headset profile, meaning you cannot use the 7100t to transfer phone numbers (and I don't think you can do addresses with any phone--I think the registered memory points and phone book are not integrated at all). I was able to transfer phone numbers using a laptop with a Bluetooth adapter. See here.

As for filtering, you can always "filter" by transfering the entries one by one. A couple limitations to keep in mind are that the characters used for the name are limited; the phone number must be just digits (I actually use XXX-XXX-XXXX format in my Outlook Express Contacts, but the transfer strips the '-'), and only one phone number can be associated per name. With these limitations, I intend to maintain a special Prius only phone list anyways, so filtering/automated synchronization is a bit of a moot point anyways.
