Summary: This is my second CK3100 Parrot. After 2 years of use the first one would not sycronize with my new Blackberry 9650 Bold. It gave a "memory full" signal. I found out on the internet that other people were having simular problems because of a design flaw. I needed to download a software patch into the unit. That was complicated and I was out of time so I am starting over.
