Gotta love the eBay sellers. The Nokia 770 is still promised by Q3 2005 (July already out, so my bet is late August, just in time for back-to-school sales), but the accessories such as screen protector are available. $14.95 buy it now.
Karoliina T. Salminen from Nokia confirms support for Bluetooth keyboards in Nokia 770:
I have seen by my own eyes bluetooth keyboard running with N770 and it works fine. However, the problem currently is the input method (virtual keyboard) which pops up when you tap some input field. If that does not bother you, the external keyboard is usable without modifications allthough is currently unsupported.
Looks like Movial is ready to fill in the missing voice communication feature for Nokia 770 - they’re providing SIP-compliant VOIP client for 770:
According to Ala-Ruona, VoIP Connect supports both iterations of SIP: IETF and IMS. While the IETF’s model for SIP is more widely used as the industry standard, cellular operators have adopted an infrastructure that uses IMS in order to better control access and usage of their closed networks. The PC client is available immediately. VoIP Connect for the Nokia 770 will be available this summer. The product was never announced because Movial didn’t want to pre-empt Nokia’s launch of the 770.
