Razr works in el Tigre flawlessly now. During development, ADC, the latest build I still did not have sync services through bluetooth. After installing the retail on my 1.67 PB 15", adding my Razr as a device did include iSynce services for Contacts and Calendars. As there are 2 possibilities for iSync, only what I just mentioned is selectable and syncs. I''m not at that machine to check now, but there was a second set of iSyncable that was not an option. May just be something that's not a phone feature. Should work though.

As this is a new PB, it does have BT 2.0. So once I finish installation on my PMG5, I get back to you as to whether the phone works with a 1.2 implemenated 10.4. Maybe there's issues. To be determined.
