This article describes how to make your applications for the Nokia Series 80 mobile phones IPv6-capable. IPv6 is supported by the new SymbianOS 8.0 network stack. Series 80 is e.g. the Nokia 9210, which of course doesn't yet support IPv6, but the newer models will. This absolutely makes sense, and I hope it will give IPv6 a higher acceptance. And, of course, mobile phone providers wouldn't have to use 10.x.y.z IPv4 address spaces for identifying mobile phones anymore.
