First, thank you for so great job

You said it doesn't support synchronization but that it add contacts in international format. So... I'm confused. I don't want to sync my phonebook because I don't want to give all my phonebook to Whatsapp Inc. Am I safe? Will you implement an option to not sync? It is a must for me.

Could it be used from PC like peterbjornx's Java port? Edit: Ops, just read that it's native for N900, so I suposse that running on PC is not possible now.

I registered with a false IMEI, and I would prefer to mantain that, but maybe I will try your program (if I could change IMEI from peterbjornx's port).
