I am interested in obtaining a Nokia N95 to use it as a mobile SIP telephone as well as a regular GSM.

I would like to have a real life experience and feedback from users who have been using it as a VoIP mobile telephone:
1) Do I have to enter the router gateway manually or I can make the telephone detect the Internet signal automatically?
2) How many Proxy servers can be registered on this telephone?
3) Does the SIP software act like an ATA with a FXO port? I mean does it offer a hop on/hop off feature with the cellular telephone line? In other words, can someone dial my cellular number and gain access to the VoIP dial tone and vice versa? I will be surprised if I find it is there.
4) Is the telephone book in this telephone gives me the choice to direct the call to the GSM or the SIP service?
5) Where can I find documentation or any demo site explaining the full features of this telephone especially the SIP part? Also a rating or a professional review site will also help.
