And I tend to agree.
Almost everything out there for Nokia N and E series phones, as well as the new dual mode Windows Mobile 6.0 handsets seems to be geared for either the 3G world or slower, or are nothing more than rewrites of apps for the personal computers.
The few apps I've seen have been mostly geared for switching or detecting WiFi (ala Birdstep) or whatever has come on the devices.
When I was at the Symbian Show in London in October nothing really was being shown that answered Dean's question. Thus the answer falls squarely on the Symbian Series 60 Developers Program and the Windows Mobile Developers to take the lead. The same with Jave Dev teams and even the Brew gang.
That's where it has to start.
